PMCLAS CITE aq ‘oihi a ; a 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, -~31- . ls eS Se GREERAETS CRS AES ee ~ aE > ERE we .
