I haven't seen it but I would consider that these are depositions in areas larger than 2 xailometers. LIBBY: What is the scale? COMAR: These are rather gross structures, on the arder of 0.1 mn There are definitely largs spots that you see vith your eyes. Anyvay, ten't it true that if you have a constant level of activity, constant through your lifetine, all this doesn't satter? COMAR: This is very true, and if you are talking about that, then assuse that even dietribution. BETHE: I think that ve can assume safely that radioactive atous are deposited the same way as nonradicactive atoms because the tbedy certainly wouldnt know the difference before they are deposited, and from what we heard before, I have assumed that strontiua is deposited the same way ag calcius and that there is no differentiation. If you are talking shout a level constant with tine through a lifetine or even level constant through enough tine to deposit, let us say 2 afllimeters of bone msterial, then it doesn't matter what the details are. You say 10 wtcroeuries equals three tenths or an r per week? BOLOMON: Z just don’t know encugh about anatomy to know vhat the travecular approach to the hematophylic system involves. to where the red cells are made or not? Dees this go down close Because if i& goes down close to where the red cells ere made, then you have got the problesa of inducive leukesia. i don't know but it ought te be taken into account. qu” ea BOE ARCHIVES wu} ~, SOLOMON:
