Dear Dr. Gregg:

I want to thank you for your letter of October 14 concerning the
questions raised by Dr. Stone in his letter to me of September 18
regarding declassification of biological and medical papers
containing information on the experimental use of radioisotopes in
human beings conducted under AEC sponsorship.

I have checked the unpublished and restricted draft of the report
of the Board of Review and note that their attitude was clearly
stated on this problem.  Accordingly, I agree with you that it is
not necessary for the Advisory Committee for Biology and Medicine
to make a further statement on this subject.

My reply to Dr. Stone included an extract of the Board of Review
remarks.  I am sure that this information will assist Dr. Stone in
evaluating the present problem and inform him as to the conditions
that must be met in future experiments.

Sincerely,

Carroll L. Wilson
General Manager
