€ell I think these things were next on the list as being LIB"Ys - dangerous. VOICES dow much lower I don't know, About 10-4, 1073 would correspond to the relative lifetines, The Ti Line energy in plutonium is much greater and my general iz pression was that an alpha-active substance is acre dangerous than a beta-active acting substance in a greater proportion and correspond just te the energy; the energy concentration seans that its zore dangerous. I'm surprised that the ratio is only 107, 1974 includes the half-life, energy and all the other FF RNs factors. Then, it probably then includes a greater collective TELL: Rs ebsorption of strontium by bone. Because, if it were only the half-life and anergy I would expect the ratie to be less. Talking about the uptake of calcius that has fallen out. B-STURN: Fe're not talking about inhalation now. There is a very large factor of diffentistion both in the uptake in: strontiua by plant end from the aptake of strontica froz the plant, ty the digestive systea. Of course, you have an additional factor there at least of the order of 1,000 to 10,000. 7 Toncrim. oj ” , ~ neq so tye ” 70
