United States
Atomic Energy Commission

June 5, 1947

Dr. Robert S. Stone

Dear Dr. Stone:

Your letter of May 7, 1947 relative to this classification of
Technical Series Volume appears to touch upon two classification
matters.

Under present policy, sections of the Technical Series Volumes
which have been de-classified through the declassification system
are, when assembled in complete Technical Series Volumes,
"Restricted".  This procedure is intended to insure that the Atomic
Energy Commission has the opportunity to evaluate the overall
affects of the compilation of such quantities of Project
information as are requested by the Series Volumes.  It is expected
that the Commission will take prompt action when the assembled
volumes have been presented for scrutiny prior to final release.

With reference to your third paragraph dealing with medical
experiments on human subjects, this action was taken upon the
advice of the Interim Medical Advisory Committee.  It is believed
that if human beings were the unwitting subjects of
experimentation, the release of information concerning such
experiments might have an adverse effect upon the position of the
Commission.  It would be perfectly proper for you to bring this
matter before the Interim Medical Advisory Committee for
Reconsideration.  It would be of assistance to them if you would
prepare specific reasons for the release of such material, taking
into full account the responsibility of the Atomic Energy
Commission in the eyes of the American people and the medical
profession on general.

Thank you for your continued interest and help in our complex
medical problems.

Sincerely,

Carroll L. Wilson
General Manager
