Dr, Bugher said there exist no unequivocal data
on this question, that it is very hard to study experimentally since
human subjects cannot be used.
He said that at the moment the data
do not support the idea that particles are more dangerous than an

evenly distributed source,
Dr. Wigner pressed for data on mice but
none were available.

In answer to Dr. Rabi, Dr. Kramish said that there are considerable fluctuations in fall-out density in the U.S., by a factor of
about 100.
Dr. Whitman pointed out that arable land might have a
greater than average fall-out, since it tends to receive more rain
and also tends to be near to targets.
It was suggested that there may be a possibility of prophylactic
control of the Sr-90 hazard by feeding people more strontium (natural
and in some cases, more calcium.
At 4:20 p.m. Dr. Smyth and Mr. Murray joined the meeting.
Dr. Kramish emphasized the importance of obtaining accurate infornation on the parameters which enter the Sunshine calculations.

the amount which has already been released (about 10 kilogrems) is
probably sufficient to be detectable in samples of inert and biological
materials throughout the world.
In addition, data are required on the
