Carbon dating non organic materials
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.
