I knew carbon dating only works back to 1950ish and anything earlier than that is no good because of all the man made radiation... but I always assumed that was from stuff like power stations etc...

I was expecting there to be about 20 test explosions.... not 2000 :s

That has to be wrong surely, the radiation associated with carbon dating is completely different than that associated with nuclear fission.

That and they've carbon dated pretty much every major archeological find.

Some radio carbon dating works very well, providing they know what they are testing and adjust for variances it can give a reasonably accurate date. Some materials just don't seem to conform to the formulas. Fabrics are particularly difficult to get an accurate test on, they have numerous bacteria which constantly produce additional fresh surface material, quite often this gives a result many hundreds of years closer to the test date than expected. The testing done on the Turin Shroud is subject to question because of this. The issue was originally discovered when testing materials from Egyptian tombs, the fabrics tested considerably more recent than bodies and wood items.

QuoteThe United Kingdom had been an integral part of the Manhattan Project following the Quebec Agreement in 1943. The passing of the McMahon Act by the United States in 1946 unilaterally broke this partnership and prevented the passage of any further information to the United Kingdom. The British Government, under Clement Attlee, determined that a British Bomb was essential. Because of British involvement in the Manhattan Project, Britain had extensive knowledge in some areas, but not in others.

An improved version of 'Fat Man' was developed, and on 26 February 1952, Prime Minister Winston Churchill announced that the United Kingdom also had an atomic bomb and a successful test took place on 3 October 1952.

Many UK military personnel were subject of exposure to radiation from the blasts, with full knowledge that it could cause cancer. This has been the subject of recent litigation within Britain.
