shortly thereafter between Bureau representatives end representatives
of the AEC the vroject was recommended for approval.
This project was
designed to provide additional information as to the contaminability and
ralnative ease of Jecontamination of a wide variety of materials 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 mde
to prevent any excessive contamination such as resulted from Operation
CROSSROADS.
The Bureau emphasized that the project:required no aiditional
personnel, and a minimum of logistical support.
Although no considerable
contemination was expected, this could not be predicted with certainty
and it seemed an opportunity to gain some valuable information.
This test would also provide information concerning the behavior of
the various particular coatings when sts}évWSNty-the fadvation spectrum

Such a test could not be duplicated with any
degree of certainty under laboratory conditions.
Approval of the project was confirmed by memorandum to the Bureau of
Shivs from the Office of Lt. General QM in carly December.

Procurement
Previously a carefully con-
trolled contamination and decontamination project at the Naval Radiation
Lebdoratory had been autho rized to survey a list of some sixty basic
materials initially, which provided a tailormade list for selection of
semple materials for the test.
The materials comprising the test panels consisted principally of
about 30 synthetic plastics, 15 types of metal finishes, and 7 rubber
