ee of BuShips to assist on the organization and vlanning of this
project.
Commans er Se arranged to procure the necessary materials
em to have them adequately calibrated at the Naval Shipyard Materiel
Laboratory, Brooklyn, New York.
This laboratory was alreedy carrying
out an extensive ‘program. to study the heat sensitivity of certain coatings for use on Naval Materiel.
Arrangements were made through Commander
Wiener, USN, of the BuShips to use the same racks for exposing the plates that were to be used for the samples being exposed by the
Bureau of Ships.
Gamma Radiation Shielding.
On 10 October 1947 the BuShips was advised that tests would be con=
ducted by the Atomic Energy Commission which would measure all the physical
phenomena associated with the detonation of an,atomic weapon.
It was
further learned that the armed services would lend logistical support
and would be permitted to make additional observations provided they
could beaiscomplished without interference with the AEC basic tests and
without materially increasing the logistical support required.
At this
wfot “
time it was understood that a rather complete ‘gamma-ray shielding program
proposed ‘bywhe AFSWP was includedgyin.the scientific program.
.
Accordingly, on 13 October BuShips submitted a letter to the Joint
Proof Test Committee outlinging its proposals for tests to beconducted «
Wank
In this letter it was requested that the Bureau of Ships be furnished a
report on the transmission of gamma rays through various shielding media.
