This matter

had been a subject of a letter from Dr. Libby in
which he suggested that Dr. Baird Hastings or
Dr. A. K. Solomon might assume this responsibility.
There was considerable discussion of the great need
for such data which are available from many sources.
The work being done by Marinelli was discussed and

the need for an expanded program of this type was agreed upon..

DR. BUGHER discussed the various means of accumulating data including
the work being done by Marinelli, the Los Alamos group, the Hanford
group and Dr. Robley Evans of MIT and pointed out the fund of information would be very valuable in reevaluating tke permissible

levels.

DR. WARREN reviewed the status of the UN Scientific Committee on the
Effects of Atomic Radiation which has a lively interest in this problem

and is working on a compilation.

This is net, however, on a crash basis

but in relation to the multiple other interests of the Committee.
DR. WARREN agreed that someone should be given the responsibility for

assembling the available data for the ACBM but suggested that the
selection of the few logical choices would result in the interruption
of a vital program. He suggested that someone not actually working

in the field but with the background and ability to appreciate it
would be a better choice.
DR. DUNHAM suggested that the first step
would probably be to call a meeting of Eisenbud, Brues, Marinelli ané

Hursh to review the problem and then decide the quickest and most

effective approach.
DR. FAILLA suggested that Dr. Robley Evans would
be an appropriate choice.
The long-term project at Utah was pointed
out by DR. DUNHAM but he said that there would Ne no answer from this
source for fifteen years.

The Chairman then called upon DR. WARREN to review the second meeting
of the UN Scientific Committee on the Effects of Atomic Radiation.
DR. WARREN suggested that the meeting started under

The most important activities had been the establish-

ment of a continuing secretariat and staff.

He

pointed out some of the continued Russian deemphasis
on genetic effects and an emphasis on neurophysiclog-

ical mechanisms.

He spoke of the sportanecus moticn

of approval of the U. S. contribution.
There had
been an extensive discussion of the genetic problem

and the recent United States and British reports

but all of the delegates concluded that while the
