Carbon dating non organic materials


Its presence in organic materials is used extensively as basis of the radiocarbon dating method to date archaeological, geological, and hydrogeological samples.— Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. — A new material with micropores might be a way to fight climate change.In sum, the proposal to use the Raes piece for C14 dating was not an academically sound proposition; it was based on expediency (as the pieces had already been removed from the relic and were "available").There is consensus now that, had the testing been allowed, it would have been the cause of great controversy regardless of the results.Regarding the Shroud, consultations should take place among archeologists, historians, conservationists, cellulose chemists and of course radiocarbon scientists in order to formulate a specific C-14 sampling and dating procedure.As I shall endeavor to demonstrate below, the radiocarbon measurement of the Shroud is a complex issue, and the inclusion of all relevant expertise is highly important.In May, 1985, I submitted such a proposal to Cardinal Ballestrero, Archbishop of Turin and official custodian of the relic, in the hope that the ecclesiastical authorities would consider appointing a scientific panel to plan and implement a C14 testing program.



Possibilities of contamination should be exhaustively investigated, and pretreatment should be devised accordingly.In contrast to these positive developments, however, there appears to be an unhealthy consensus approaching the level of dogma among both scientific and lay commentators, that C-14 dating will "settle the issue once and for all time."This attitude sharply contradicts the general perspective of field archaeologists and geologists, who view possible contamination as a very serious problem in interpreting the results of radiocarbon measurement.In this paper I shall examine the issue of the reliability of C-14 testing to produce an "absolute date" on the linen sheet known as the Holy Shroud of Turin and believed by some to be the gravecloth of Christ.Much worse, the 1979 proposal involved a small sample of cloth removed from the Shroud in 1973 for study by Prof. Mc Crone and Sox had inspected the sample (apparently unstitched by Raes into two pieces) during a visit with Raes in 1976, and found that "the samples were kept in what looked like an old scrapbook for postage stamps" (Sox: 19).

Certainly most archaeologists would have rejected the use of samples subjected to a long separation from the object to be dated and held under unknown conditions of storage and handling.

Buckyball sandwiches combine fullerenes and graphene. Scientists have created crystals that capture carbon dioxide much more efficiently than previously known materials, even in the ...
