D.s, and other qualified individuals connected with certain medical and emergency agencies in Los Angeles and funded by the Department of Homeland Security. Non-availability of supplies and drugs - and no way to transport them if they were available somewhere. Serious limitations regarding availability of communications systems. Total lack of personnel trained to respond to the situation.

'Decorporation' Drugs "For example, Los Angeles County has stockpiled drugs that help remove internalized radioactive material from the body.

These drugs are called 'decorporation' drugs, and they may be accessed by physicians managing radiocontaminated patients in whom decorporation appears to be clinically appropriate.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.

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.

Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
