that report do not apply to any atomic tests conducted in Nevada. It is completely erroneous to assume that every nuclear explosion, regardless of size or point of burst, creates a fallout danger over thousands of square miles and ranging several hundred miles down-wind from the point of burst, the case, This is not The explosion at Bikini occurred on the surface of the island, The fallout, therefore, resulted from both the tremendous explosive power and the fact that the fireball touched the surface of the earth. An atomic device of the type now being tested in Nevada detonated under the same conditions as those of the Bikini explosion would have produced oniy @ very small fraction of the fallout, Likewise, if the Bikini H-bomb had been exploded high in the air, the amount of radicactive particles in the bomb cloud would have been a very small fraction of that produced by the surface explosion, The particles would have been smaller and lighter and therefore wculd have been carried by the wind over a greater distance. ‘This would have meant greater diffusion from the air currents and greater loss of radioactivity due to decay than was actually the case when the Bikini H-bomb was exploded on the surface, The yields (energy release) of the atomic devices tested at the Nevada site are actually tiny by comparison with the thermonuclear weapons whose testing is confined to a remote area of the Pacific, cman ~ 3 ei -
