Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calculate when the animal or plant died. The older a sample is, the less 14 C there is to be detected, and because the half-life of 14 C the period of time after which half of a given sample will have decayed is about 5, years, the oldest dates that can be reliably measured by this process date to approximately 50, years ago, although special preparation methods occasionally permit accurate analysis of older samples.

At higher temperatures, CO 2 has poor solubility in water, which means there is less CO 2 available for the photosynthetic reactions. The enrichment of bone 13 C also implies that excreted material is depleted in 13 C relative to the diet. The carbon exchange between atmospheric CO 2 and carbonate at the ocean surface is also subject to fractionation, with 14 C in the atmosphere more likely than 12 C to dissolve in the ocean.

This increase in 14 C concentration almost exactly cancels out the decrease caused by the upwelling of water containing old, and hence 14 C depleted, carbon from the deep ocean, so that direct measurements of 14 C radiation are similar to measurements for the rest of the biosphere.

Correcting for isotopic fractionation, as is done for all radiocarbon dates to allow comparison between results from different parts of the biosphere, gives an apparent age of about years for ocean surface water. The marine effect : The CO 2 in the atmosphere transfers to the ocean by dissolving in the surface water as carbonate and bicarbonate ions; at the same time the carbonate ions in the water are returning to the air as CO 2.

The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven. The main mechanism that brings deep water to the surface is upwelling, which is more common in regions closer to the equator. Upwelling is also influenced by factors such as the topography of the local ocean bottom and coastlines, the climate, and wind patterns. Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO 2 with the surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years.

Upwelling mixes this "old" water with the surface water, giving the surface water an apparent age of about several hundred years after correcting for fractionation. The northern and southern hemispheres have atmospheric circulation systems that are sufficiently independent of each other that there is a noticeable time lag in mixing between the two. Since the surface ocean is depleted in 14 C because of the marine effect, 14 C is removed from the southern atmosphere more quickly than in the north.

For example, rivers that pass over limestonewhich is mostly composed of calcium carbonatewill acquire carbonate ions. Similarly, groundwater can contain carbon derived from the rocks through which it has passed. Volcanic eruptions eject large amounts of carbon into the air.

Dormant volcanoes can also emit aged carbon. Any addition of carbon to a sample of a different age will cause the measured date to be inaccurate. Contamination with modern carbon causes a sample to appear to be younger than it really is: the effect is greater for older samples. Samples for dating need to be converted into a form suitable for measuring the 14 C content; this can mean conversion to gaseous, liquid, or solid form, depending on the measurement technique to be used.

Before this can be done, the sample must be treated to remove any contamination and any unwanted constituents. Particularly for older samples, it may be useful to enrich the amount of 14 C in the sample before testing.

This can be done with a thermal diffusion column. Once contamination has been removed, samples must be converted to a form suitable for the measuring technology to be used.

For accelerator mass spectrometrysolid graphite targets are the most common, although gaseous CO 2 can also be used. The quantity of material needed for testing depends on the sample type and the technology being used.

There are two types of testing technology: detectors that record radioactivity, known as beta counters, and accelerator mass spectrometers. For beta counters, a sample weighing at least 10 grams 0. For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the 14 C in a sample was to detect the radioactive decay of individual carbon atoms. Libby's first detector was a Geiger counter of his own design.

He converted the carbon in his sample to lamp black soot and coated the inner surface of a cylinder with it. This cylinder was inserted into the counter in such a way that the counting wire was inside the sample cylinder, in order that there should be no material between the sample and the wire. Libby's method was soon superseded by gas proportional counterswhich were less affected by bomb carbon the additional 14 C created by nuclear weapons testing.

These counters record bursts of ionization caused by the beta particles emitted by the decaying 14 C atoms; the bursts are proportional to the energy of the particle, so other sources of ionization, such as background radiation, can be identified and ignored. The counters are surrounded by lead or steel shielding, to eliminate background radiation and to reduce the incidence of cosmic rays.

In addition, anticoincidence detectors are used; these record events outside the counter and any event recorded simultaneously both inside and outside the counter is regarded as an extraneous event and ignored.

The other common technology used for measuring 14 C activity is liquid scintillation counting, which was invented inbut which had to wait until the early s, when efficient methods of benzene synthesis were developed, to become competitive with gas counting; after liquid counters became the more common technology choice for newly constructed dating laboratories. The counters work by detecting flashes of light caused by the beta particles emitted by 14 C as they interact with a fluorescing agent added to the benzene.

Like gas counters, liquid scintillation counters require shielding and anticoincidence counters. For both the gas proportional counter and liquid scintillation counter, what is measured is the number of beta particles detected in a given time period. This provides a value for the background radiation, which must be subtracted from the measured activity of the sample being dated to get the activity attributable solely to that sample's 14 C.

In addition, a sample with a standard activity is measured, to provide a baseline for comparison. The ions are accelerated and passed through a stripper, which removes several electrons so that the ions emerge with a positive charge. A particle detector then records the number of ions detected in the 14 C stream, but since the volume of 12 C and 13 Cneeded for calibration is too great for individual ion detection, counts are determined by measuring the electric current created in a Faraday cup.

Any 14 C signal from the machine background blank is likely to be caused either by beams of ions that have not followed the expected path inside the detector or by carbon hydrides such as 12 CH 2 or 13 CH. A 14 C signal from the process blank measures the amount of contamination introduced during the preparation of the sample.

These measurements are used in the subsequent calculation of the age of the sample. The calculations to be performed on the measurements taken depend on the technology used, since beta counters measure the sample's radioactivity whereas AMS determines the ratio of the three different carbon isotopes in the sample. To determine the age of a sample whose activity has been measured by beta counting, the ratio of its activity to the activity of the standard must be found.

To determine this, a blank sample of old, or dead, carbon is measured, and a sample of known activity is measured. The additional samples allow errors such as background radiation and systematic errors in the laboratory setup to be detected and corrected for.

Opinion you radiocarbon dating manuscripts remarkable, rather useful

The results from AMS testing are in the form of ratios of 12 C13 Cand 14 Cwhich are used to calculate Fm, the "fraction modern". Both beta counting and AMS results have to be corrected for fractionation.

The calculation uses 8, the mean-life derived from Libby's half-life of 5, years, not 8, the mean-life derived from the more accurate modern value of 5, years. Libby's value for the half-life is used to maintain consistency with early radiocarbon testing results; calibration curves include a correction for this, so the accuracy of final reported calendar ages is assured.

The reliability of the results can be improved by lengthening the testing time. Radiocarbon dating is generally limited to dating samples no more than 50, years old, as samples older than that have insufficient 14 C to be measurable. Older dates have been obtained by using special sample preparation techniques, large samples, and very long measurement times. These techniques can allow measurement of dates up to 60, and in some cases up to 75, years before the present.

This was demonstrated in by an experiment run by the British Museum radiocarbon laboratory, in which weekly measurements were taken on the same sample for six months. The measurements included one with a range from about to about years ago, and another with a range from about to about Errors in procedure can also lead to errors in the results.

The calculations given above produce dates in radiocarbon years: i. To produce a curve that can be used to relate calendar years to radiocarbon years, a sequence of securely dated samples is needed which can be tested to determine their radiocarbon age. The study of tree rings led to the first such sequence: individual pieces of wood show characteristic sequences of rings that vary in thickness because of environmental factors such as the amount of rainfall in a given year.

These factors affect all trees in an area, so examining tree-ring sequences from old wood allows the identification of overlapping sequences. In this way, an uninterrupted sequence of tree rings can be extended far into the past. The first such published sequence, based on bristlecone pine tree rings, was created by Wesley Ferguson. Suess said he drew the line showing the wiggles by "cosmic schwung ", by which he meant that the variations were caused by extraterrestrial forces.

It was unclear for some time whether the wiggles were real or not, but they are now well-established. A calibration curve is used by taking the radiocarbon date reported by a laboratory and reading across from that date on the vertical axis of the graph. The point where this horizontal line intersects the curve will give the calendar age of the sample on the horizontal axis. This is the reverse of the way the curve is constructed: a point on the graph is derived from a sample of known age, such as a tree ring; when it is tested, the resulting radiocarbon age gives a data point for the graph.

Over the next thirty years many calibration curves were published using a variety of methods and statistical approaches.

The improvements to these curves are based on new data gathered from tree rings, varvescoralplant macrofossilsspeleothemsand foraminifera. The INTCAL13 data includes separate curves for the northern and southern hemispheres, as they differ systematically because of the hemisphere effect.

The southern curve SHCAL13 is based on independent data where possible and derived from the northern curve by adding the average offset for the southern hemisphere where no direct data was available. The sequence can be compared to the calibration curve and the best match to the sequence established. This "wiggle-matching" technique can lead to more precise dating than is possible with individual radiocarbon dates. Bayesian statistical techniques can be applied when there are several radiocarbon dates to be calibrated.

For example, if a series of radiocarbon dates is taken from different levels in a stratigraphic sequence, Bayesian analysis can be used to evaluate dates which are outliers and can calculate improved probability distributions, based on the prior information that the sequence should be ordered in time.

Radiocarbon dating manuscripts

Several formats for citing radiocarbon results have been used since the first samples were dated. As ofthe standard format required by the journal Radiocarbon is as follows. Related forms are sometimes used: for example, "10 ka BP" means 10, radiocarbon years before present i. Calibrated dates should also identify any programs, such as OxCal, used to perform the calibration. A key concept in interpreting radiocarbon dates is archaeological association : what is the true relationship between two or more objects at an archaeological site?

It frequently happens that a sample for radiocarbon dating can be taken directly from the object of interest, but there are also many cases where this is not possible. Metal grave goods, for example, cannot be radiocarbon dated, but they may be found in a grave with a coffin, charcoal, or other material which can be assumed to have been deposited at the same time.

As a test, inWillard Libby and his team took samples of acacia from two ancient Egyptian Old Kingdom rulers and dated them. Therefore, it is clear that radiocarbon dating is not based on some imprecise science, cooking up evidence to fit the idea or data. On the other hand, palaeography is a relative dating method which gives an order of events without giving an exact age.

Thus, generally speaking, it cannot be used to pinpoint dates with high precision. Is palaeography a form of science? Commenting on the issues regarding the dating of ancient Hebrew inscriptions, William M. Schniedewind says:. The so-called science of paleography often relies on circular reasoning because there is insufficient data to draw precise conclusion about dating.

Scholars also tend to oversimplify diachronic development, assuming models of simplicity rather than complexity. In other words, palaeography can at best be termed as an inexact science, filled with uncertainties and imprecisions.

It is not judicious to upscale palaeography for its reliability whilst, on the other hand, putting down radiocarbon dating for its alleged lack thereof. So, what is the general "rule of thumb" followed in dating manuscripts via palaeography? This kind of precision dating defies the realities of scribal activity.

The productive writing life of a scribe was probably around thirty or thirty-five years. Add to that the fact that the scribal profession was an apprenticed trade, with students learning a particular style from a teacher, and we find that a given hand may be present over multiple generations of scribes.

Thus the "rule of thumb" should probably be to avoid dating a hand more precisely than a range of at least seventy or eighty years. This is comparable with the "rule of thumb" of at least a range of 70 to 80 years used in palaeography for dating a manuscript.

Unlike radiocarbon dating, it is worth noting that a range of 70 to 80 years used in palaeography has no confidence level attached to it.

The choice of whether to believe in such a "confidence level" is entirely up to an individual. In any case, the Birmingham results suggest that Lyon might not have botched the job after all. Intriguingly, the first date range from Lyon - corresponds rather closely to the date range given from a laboratory in Oxford for the Birmingham manuscript - What is telling here is the fact that Reynolds, instead of using a scientific approach to look at the problem, applies his own reasoning that must necessarily accord with his preferred historical interpretation.

thanks for

How does one make a rational choice as to which date, if any, out of these three is correct? The answer is that there is no way of knowing if Lyon botched the job unless these three dates are independently compared with those obtained from other labs. Reynolds makes no attempt to use the scientific method here. He says. Nevertheless, the dating of these manuscripts has proven to be highly problematic and controversial.

Suffice to say that the process of radiocarbon dating does not seem to be working accurately on these materials. For instance, one such manuscript, now in Birmingham, England, has been given a date range that places it before Muhammad began his religious movement. It is not clear why the radiocarbon dating of these manuscripts is inaccurate. Furthermore, how does Shoemaker know that the dating is inaccurate?

He has not published any independent, consistent, and reliable radiocarbon data for each of these manuscripts that could substantiate his claim. It is worthwhile pointing out that when applied to parchments in fields other than Qur'anic studies, radiocarbon dating has yielded results that are "generally Here the problem may lie with the conditions arid or semi-arid climate under which the cattle, the hides of which were later turned into parchment, was raised.

Thus, according to his view, the arid or semi-arid climate in which the parchment for Qur'anic manuscripts were produced does not lend itself to accurate radiocarbon dating. There are numerous problems with this view. As we had noted earlier, radiocarbon 14 C is produced via the cosmogenic process and this happens at stratospheric altitudes of 9 to 15 km above the surface of the Earth.

In general, the cosmic rays flux remains constant and observed fluctuations in production rate of 14 C are controlled by geomagnetic field strength and solar activity. Thus seasonal changes and presence of moisture on the surface of the Earth have no effect on the production rate of 14 C. What about the variation of decay of radiocarbon 14 C due to the chemical environment around the atom? Thus, the variation of just a percentage or so, is much too small to affect Earth's overall time scale and consequently the radiocarbon dating itself.

If one were to instead use the data from the southern hemisphere and we are talking about Arabia hereI am told by those more expert in this procedure than me that very different datings would result. To begin with, Arabia is not in the Southern Hemisphere. It is situated in the Northern Hemisphere between the latitudes The Tropic of Cancer at As for the global atmospheric radiocarbon content, it is controlled by several factors such as climatic changes, oceanic circulation, solar output and geomagnetic variability.

It has been demonstrated that Southern Hemisphere samples have lower 14 C contents. The question now is how much older are the radiocarbon samples from the Southern Hemisphere compared to the Northern Hemisphere?

Furthermore, it is not surprising that the calibration data set for the Northern Hemisphere IntCal series is different from that of the Sourthern Hemisphere SHCal seriesand that these are frequently ated to fine tune the respective calibration curves. That is, these manuscripts are from the 1st century of hijra. Shoemaker's argument against radiocarbon dating shifts from raising the inter-hemispheric offset to intra-hemispheric changes in radiocarbon content.

The problem, it would seem, is that radiocarbon dating in the medieval period is only accurate when it can be calibrated by tree ring data, particularly from oak trees. Such data is wanting for the medieval Mediterranean or Near East, and the data from the northern hemisphere that has been used to calibrate these tests was taken from Ireland and North America. There are several inaccuracies in the above statements. The work of the Aegean Dendrochronology Project started in s and since then it has continued since to build the long tree-ring chronologies for the eastern half of the Mediterranean.

Its aim was to make scientific sense of the Aegean and Near Eastern chronology from the Neolithic Age to the present. The most recent state as of late of the Aegean tree-ring chronology is shown in Figure 23 which also appeared in a slightly expanded form in Figure The state of Aegean tree-ring chronologies as of late This is an ate of the bar graph published in Less common species such as boxwood and yew are removed in this plot.

Source: Aegean Dendrochronology Project. Now that we have established the fact that the dendrochronological data from oak trees among others already exist, let us now look into the issue of calibration. Shoemaker says that since the calibration is done using the tree-ring data from Ireland and North America, it can't be trusted for dating medieval Mediterranean and Near East samples. The tacit assumption of his claim is that the chronology derived from the tree-ring data from Ireland and North America is very different from what is obtained from the Mediterranean and Near East samples.

One of the fundamental tenets of radiocarbon dating is that within each hemisphere there was sufficient mixing of the pre-industrial atmosphere to allow the use of a universal 14 C calibration dataset.

On the issue of calibration, it must be mentioned that the dendrochronological database for the IntCal04 curve is largely similar to the dataset of the IntCal98 curve, but also includes new measurements for the Iron Age period, for example, German Oak samples run for the East Mediterranean Radiocarbon Comparison Project. A trial run of the model against the IntCal04 calibration curve gave essentially similar results, albeit that the dates become slightly older.

Reynolds, on the other hand, claimed that the dating of Dead Sea Scrolls may be considered more accurate than the dating of manuscripts of Qur'an. His reasoning is as follows:. This allows scientists to calibrate their measurements more precisely.

This is entirely erroneous. The tree ring atmospheric radiocarbon calibration data set spanning 0 to 12, years BP is used Figure It is superior to all other atmospheric radiocarbon calibration data due to the number and quality of the radiocarbon measurements and the accuracy and precision of the tree dendrochronology.

Figure Schematic diagram of IntCal04 and Marine04 calibration data set construction. The IntCal09 uses a similar data set. The scrap of linen and piece of leather are dated using the standard calibration data set. It appears that Reynolds does not properly comprehend how radiocarbon calibration curves are constructed.

Strained, arbitrary and impossible interpretations of science, in our case of the science of radiocarbon dating, can lead to endless possibilities, i. We have already seen specific examples in the above sub-sections. Here we are going to deal with historical constructions or possibilities that are a result of interpretations of radiocarbon dating, more specifically of the Mingana folios at Birmingham.

Jun 17,   Although the New Testament as we know it is essentially a "collage" of various surviving manuscripts, it relies heavily on one particular, parchment manuscript-the fourth-century Codex Vaticanus, or the Vatican the midth century, explains Nongbri, "most New Testament textual critics believed that the text of the New Testament preserved in the Codex Vaticanus was the result. Radiocarbon dating of Qur'anic manuscripts is very rare, though this is beginning to change. With the advent of the Corpus Coranicum project, carbon dating has been given pride of place with a specially named module Computatio Radiocarbonica. The aim here is to supplement traditional methods for dating the earliest Qur'anic manuscripts with. Manuscripts may be submitted to RADIOCARBON at any time, using the online submission of this system ScholarOne. Professional Considerations Authors listed on the title page should all have had some involvement in the writing of the article and/or the research and development underlying it.

Parchment was an expensive material the skin of the entire animal was used to produce the big folio. These stocks became part of the loot captured by the Arabs in the first years of the conquest. To test this hypothesis, it is necessary to reread the existing historical sources dedicated to the first years of the Arab conquests. In essence, one is asked to believe in the fantastic hypothesis that the people of Greater Syria among other places stocked already prepared blank parchment and were eagerly awaiting the advent of Islam and Arab conquests in order to hand them willingly this valuable possession.

One is led to believe unused parchment had been left for years! Why would the seller s expend an enormous amount of time, money and effort to prepare a multitude of blank parchment with no customer or no prospect of a customer?

This in itself is self-contradictory and it assumes a thriving market. Additionally, if a client could afford to have such a codex constructed, why would one rely on parchment that is years or generations old? Rich patrons presumably could afford brand new parchment, given the likely deterioration of prepared stocked parchment that is over half a century in age.

Did the new rulers and their subjects need recourse to stocked parchment?

How Does Radiocarbon Dating Work? - Instant Egghead #28

As far as we are aware there are no examples from early Islamic history where the Muslims were unable to execute a writing project because of the lack of prepared stocked parchment. Common sense dictates if the Muslims desperately needed parchment to write on, they could have simply requested already used parchment, religious or otherwise, scraped it clean and started writing.

All of the preceding assumes the existence and logical necessity of prepared stocked parchment that is years old. Rezvan cites no historical sources supportive of his hypothesis, and, as far as we are aware, there is no recorded instance around the time of late antiquity of prepared blank parchment being deliberately stored for such an extensive period of time.

Unfortunately, his misunderstanding of the radiocarbon date range has resulted in him adopting an ad hoc randomly generated number range to satisfy his hypothesis retrospectively. He concludes. Reynolds has expended a not inconsiderate amount of effort explaining, identifying and at times advocating John Wansbrough's theories, including Wansbrough's now abandoned theory of a late compilation of the Qur'an.

There is not the slightest hint of historical context that necessitates the wholesale re-writing of the Late Antiquity, including nascent religious movements, inter-religious dynamics, Arabic palaeography, codicology, scribal culture and book culture. This kind of irresponsible flip-flopping is unlikely to benefit the field of Qur'anic studies and leaves the author's stated position on this most important issue confused and uncertain. There is an important methodological principle to be observed here.

Arabe a and Ms. With the benefit of further examination and additional evidence, he has since revised his views and now considers them as emanating from the same manuscript. One must be very careful not to make assumptions and generalisations on the basis of a few tests.

As described in the previous section, sample pretreatment is absolutely critical if one wants to obtain the most accurate measurements. Who then should have the final say in matters relating to dating? It may seem what is at stake here is the historian's craft. Spending decades honing skills learnt from masters in the field, it is only natural to encounter some pushback against a recently developed detached scientific method, especially when it appears to undermine commonly accepted historical paradigms.

However, there need not be any confrontation. One of the great benefits and advantages of radiocarbon dating is that scholarly prejudice and pre-suppositions about the genesis of Arabic scripts and Qur'anic manuscripts are not factored into the calculation. It cannot, however, be seen as disadvantageous or faulty when it appears to clash with one's own chronological reconstruction.

A collaborative approach that makes full use of scientific tests whilst remaining anchored in time tested traditional historical methods is more likely to provide the most fruitful results. The invention of radiocarbon dating has been revolutionary for the humanities. Nevertheless, one of the downsides are the potential large time intervals which do not prove very useful in dating manuscripts very precisely, though this has been mitigated somewhat by the year on year improvement in accuracy and precision.

At the outset when this technique was being considered for application to the Qur'an, specialists were rightly cautious and skeptical regarding the usefulness of the expected results.

Writing inGerd-R. Puin pointed out radiocarbon dating had results scattered over a large time period, sometimes spanning a few hundred years. He suggested the traditional methods of Arabic palaeography were more precise and offered a smaller range for dating Qur'anic manuscripts. Since then much progress has been made in the intervening thirty-five years.

One can take a positive view of the science and see in the interpretation of its results an avenue of further enquiry into the examination of Islamic origins.

Radiocarbon dating was not developed as a tool to advance the traditional account of the compilation and transmission of the Qur'an, though this is the impression one may be left with reading certain scholarly articles and popular level works written by scholars. Faulty understanding of the scientific principles underpinning this radiometric dating technique have caused some modern scholars working in Islamic Studies to imagine improbable and sometimes absurd hypotheses.

Some seem to suggest the wholesale dismissal of this technique. Others that this technique doesn't work for the Qur'an.

May 23,   This ate makes the article "Radiocarbon (Carbon) Dating Of The Manuscripts Of The Qur'an" the most comprehensive listing of radiocarbon dated Qur'an's published so far in print or online. By Paul Williams on May 23, (1). Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in More information on Dead Sea scroll dating can be found in the journal Radiocarbon vol.3 Carbon dating has verified hundreds of archaeological sites mentioned in the Bible. Over 57, readable clay tablets in Mesopotamia and many Egyptian Papyrii have shown that even many slaves could write in Abraham's time.

Key terms and concepts such as probability, accuracy and precision are found to be poorly understood. A common feature of the aforementioned criticisms, at present without exception, is the absence of any peer reviewed scientific literature supportive of such views. Instead recourse is made to informal scientific conversation occasionally referencing unnamed persons.

Some of the discussion seems strained to coincide with the authors preferred historical reconstruction. Our investigation points to the fact that even though the palaeographic and radiocarbon results usually match each other, the scientific method of radiocarbon dating can assist in generating and informing the debate regarding the chronology of Qur'anic manuscripts. In fact, more than thirty-five years ago similar conclusions were reached for the Dead Sea Scrolls using radiocarbon and palaeographic datings.

The radiocarbon method can only supplement, and at times complement, the traditional method of palaeography and is gaining prominence in dating. As the accuracy and precision of radiocarbon dating improves with every passing year, one would be wise to take heed of Blair's insistence on utilising a more comprehensive approach than is currently the case, insisting that the adoption of multi-disciplinary sophistication will help to solve the disputes on dating early Qur'anic manuscripts.
