The Shroud of Turin", by D. Christopher Ramsey, the director of the Oxford Radiocarbon Laboratory, thinks more testing is needed. Retrieved 19 April Of the human mtDNAsequences were found belonging to haplogroups that are typical of various ethnicities and geographic regions, including Europe, North and East Africa, the Middle East and India. Before the advent of radiocarbon dating, the fossilized trees had been dated by correlating sequences of annually deposited layers of sediment at Two Creeks with sequences in Scandinavia. Advances in Chemistry. Korffthen employed at the Franklin Institute in Philadelphiathat the interaction of thermal neutrons with 14 N in the upper atmosphere would create 14 C.
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.
Radiocarbon dating of the Shroud of Turin
According to the art historian Nicholas Allen, the image on the shroud was formed by a photographic technique in the 13th century. Retrieved 31 July However, in a paper Gove conceded that the "arguments often raised, … that radiocarbon measurements on the shroud should be performed blind seem to the author to be lacking in merit; … lack of blindness in the measurements is a rather insubstantial reason for disbelieving the result. Related forms are sometimes used: This paper is significant in that it was presented to the international radiocarbon community shortly before radiocarbon dating was performed on the shroud. If so, the restoration would have had to be done with such incredible virtuosity as to render it microscopically indistinguishable from the real thing. Retrieved 24 January
