Dear Dr. Lederberg:

I am enclosing a copy of a paper I presented in a symposium at the recent
AAAS meeting in Boston. I am also enclosing a copy of a paper by Dr. Meyer,
et al which I discuss in the section of my paper"Genetic Consequences of
Radiation;" beginning on page 17.

I feel that the results reported in the paper by Meyer are very significant
to this whole problem. TI was appalled to discover that members of the
International Commission on Radiological Protection such as Dr. Dunster and
geneticists of the AEC's Division of Biology and Medicine were unaware of
the study even though the original report appeared in 1967. This study would
appear to support your statement in your recent article in the Chronicle that
future studies would most likely show the effects of radiation to be worse
than that presently assumed. I would appreciate your comments of this and
my discussion of it in the AAAS report.

Sincerely yours,

Lhgther 2. Laid lew
