CONCEALMENT OF UNDERGROUND EXPLOSIONS
The Cowboy experiments on decoupling of underground nuclear explosions show that the principle of decoupling by means of a large hole is correct. The decoupling factor of 300 estimated in RAND Report R-348 is still the best estimate for a hole in salt relative to a tamped shot in Nevada tuff. It was found that decoupling is not an all or none effect and that, if the elastic limit of the medium is exceeded, the decoupling factor is reduced, but only gradually. As a result it appears possible to explode a 20-kt device in a cavity no bigger than some which already exist, without prcducing a signal that could be detected by the Geneva system. (auth)
