I am asking about the strength. Buck: Is one stronger, more powerful bomb than the others? ~: Yes, there were much stronger, more powerful bombs than in the late years at Bikini and Enewetak than any that we had ever used before. The strength of the radiation from any given element was the same no matter what the bomb source was. Cowan: Are you saying that those are fission fragments and daughter products from the fission bomb? ~: Yes, of course. Well, there are fission products resulting from every bomb that we have tested. Cowan: But you are saying that the radiation produced was the same for fission or fusion explosions? ~: For any given radionuclide the radiation coming from that material is the same no matter what the source of that material is. Does that answer your question? Cowan: Not exactly. I’m looking at the fragments and the daughter products not being the same. M_y: The fragments of, let’s say, cesium-137 coming from a bomb that was fi~ed over Nagasaki, Hiroshima, Bikini or Enewetak, that cesium-137 is the same. As it decays, it decays into the same family of end products or daughter products, and they have the same energy, they radiate with the same intensity. Cowan: The same products were created in Nagasaki and Hiroshima as was created at Bikini and Enewetak? 19
