RADIATION STANDARDS, INCLUDING FALLOUT
Mr. Ramey. Would it be possible to give us a little supplementary
statement on how much moneyis being expended in this generalfield
comparable to the statement you gave us a few years ago?
Dr. Dunyuam. Wewill be happy to prepare one.
Chairman Hotuteip. Did you ever get into the large animal experiments that we talked about'a year or two ago?
;
Dr. Dunnam. Thatis the one about which we had this meeting with
the group from Argonne and Oak Ridge. Oak Ridge will do the
whole body external studies in 10 to 20 thousand mice per experiment.
The Argonne will do it with strontium 90 and some of the
other internal emitters. There is also developing a fairly large-scale
dog program at Argonne.
Representative Price. You were talking about larger facilities for
cattleand soon. You were talking about those at one time.
Dr. Dunnam. Wehave not gotten into really large-scale studies in
cattle. The expense goes up quite a little when you go into that. We
have the swine project at Jowa which is a straight quantitative genetics
project which involves six to eight thousand little piglets born every
year.
Chairman Hortrietp. That is a considerable advance over what you
had a few years ago.
Dr. Dunuam. Definitely.
Chairman Hoxirteip. We were not in this swine workat all hardly.
Dr. Dunnam. No; we were not doing it before. I think we are
definitely moving outof the horse-and-bugey stage and try to catch up
with our other programs, with Dr. Russell’s work, which sort of set
the pattern of what can be done. Youare familiar with his results in
genetics studies.
Chairman Houtrtetp. With mice you can do it much cheaper?
Dr. Dunuam. Much cheaper.
Chairman Hoirretp. What about the comparative results in extrapolation from mice or swine?
Dr. Dunnam. This is why we have chosen some other species to
go into, like the swine, simply so we don’t get caught with something
very unusual about the mouse that is not the case in swine. We are
doing it also in rats.
Chairman Houtrirtp. The question is whether man resembles a
mouseor a pig.
Dr. Dunnam. In somerespects the man’s hide from what the dermatologists and people studying flash burns say is much morelike that
of a pig thanit is of a mouse. On the other hand, as you know,alcohol
protects a mouse against radiation but in terms of a man the dose
would be a little lethal.
Chairman Ho.trtety. I knew there was some good in alcohol.
Representative Price, Will the U.S. space programs such as Rover
produce fallout ?
Dr. Dunuam. Not of the sort of thing we are talking about with
megaton weapons. There is the problem as the program gets uncerway, particularly if they begin to use the Rover devices as thefirst
stage of a certain amount of fissionable material being released. We
are talking im terms of something comparable to very low kiloton
cletonations. It will be released along the way. If one of these devices
after it has been used up were to reenter and burn up completely in the
