A new project was officially submitted by the Bureau of Ships
to the Joint Proof Test Cammittee on 13 October 1947.

‘

At a conference

hold shortly theroafter between Bureau representatives and represontatives of the AEC the project ras recommended for approval,

This

project was designed to provide additional infarmtion as to tho
contaminability and relative ease of decontamination of a wide variety
of miterials which could conceivably be used as protective coatings

'

on Naval equipment and structures,
At this conference it was pointed out that an effort would be made

'

to prevent any axcessive contamination such as resulted fran Qperation
CROSSROADS.

The Bureau emphasised that the project required no addition

al personnel, and a minimm of losistical support.

Althoush no con-

sidorable contamimtion was expected, this could not be predicted with
certainty and it seemed an opportunity to sain sone valuable information.
This test would also provide information concerning the behavior

.

spectrum produced by the weapon.

Bn tie

of the various particular coatings when subjected to the radiation
Sich a test could not be duplicated

with any desree of certainty under laboratory comlitions,
Approval of the project was confirmed by memorandwa to the Bureau
of Ships fran the Office of Lt, General Hull in early December,

curement of samples of mterials was then initiated.

FPro-

Freviously a

carefully controlled contamination and decontamination proJect at the

Naval Radiation Laboratory had been authorised to survey a list of some
sixty bdsic materials initially, which provided a tailer-mide list for
selection of sample miterinls for the test,
