Felt SUBJECT: ON-SITE RAD-SAFE AT NEVADA PROVING GROUND SYMBOL : d=15G-57 BEST COPY AVAILABLE This memorandum results from the airing.at a recent Pogo meeting of views and complaints about Rad-Safe at NPG. In every test series we seem to make a little headwey and learn a little more about what we might try the next time. In the last few days I have talked the thing over with Carl Lyon and we have arrived at a scheme which we believe is workable and meets at least some of the major complaints. Before outlining the plan I would like to explain why it is mecessary to have Rad~Safe at all, and why at NPO the orgenization is run by militery peoples I think we can all agree that there is such a thing as a radiological hazard to people even though many of the details are mt known. We are not certain of the precise physiological effects of each of the active elenents but the garsral effects are at least limned. Many of us have sgen or heard of skin burns and radiation sickness. A lot of work on ra- diation effects has been done at our own laboratory. In addition the laboratory exercises a very tight control over enployees whose work ex- poses them to radiation. We have a whopping lot of Rad-Sefe right here, operating according to a set of rules designed to protect our people. ‘ Among the rules is the familiar 0.3 r per week y tolerance. Those of us who are experimenters I think will all agree that it is also necessary to keep certain types of equipment and materials "clean" in ordcr to do our work. The Health Division keeps a careful watch over the laborc- tory for this reason too. It is at least as important at NPG as it is here that the same sort of steps be taken to protect people and equipment. Evan if we had NFO to ourselvas, as we orce fondly hoped, it would be necessary to have some kind of Rad-Safe control. In the first two operations at NPQ Rad-Safe could be and was run by H-Divisiono The effect at the laboratory wes similar to that of the Crossroads exodus and EONFIRMED TO BE UNCLASSIFIED BY ee,F DoE! oo COPIEDy: LANL RC Crt (Dame ,Lbs 5 IRS See A EEST ; pate '
