Does radioactive dating work for gases

ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.

Photography of the shroud by Secondo Pia in 1898 indicated that the image resembled a photographic 'negative' and represents the first modern study.

Subsequently the shroud was made available for scientific examination, first in 19 by a committee appointed by Cardinal Michele Pellegrino .

Even for the first investigation, there was a possibility of using radiocarbon dating to determine the age of the linen from which the shroud was woven.

The size of the sample then required, however, was ~500cm, which would clearly have resulted in an unacceptable amount of damage, and it was not until the development in the 1970s of small gas-counters and accelerator-mass-spectrometry techniques (AMS), requiring samples of only a few square centimetres, that radiocarbon dating of the shroud became a real possibility. The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.

They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.

This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

It was first displayed at Lirey in France in the 1350s and subsequently passed into the hands of the Dukes of Savoy.

After many journeys the shroud was finally brought to Turin in 1578 where, in 1694, it was placed in the royal chapel of Turin Cathedral in a specially designed shrine.

amount of radiocarbon, or carbon-14, remaining in an object to determine its approximate age.
