I strongly feel that thea best protection that this netion oan mee me secure acainst tho possibilities of radiotctive azents veing omployed as amilitary tool by some foreign power is a thorough evaluation and under-~ . standing of the full potentiality of such an agent. Fven if it were possible to predict the evil consequences that will result from the use of such an uplyasent military implement, such canolusiongs that could be mado would be inadequate. In other words, I believe that it is necessary for the adequate defensos of this nation that’ ean active and comprehensive examination of the entire problem be made by the armad services. Suchia program, I feel should ! bo carricd out by the Chemical Verfare Service with the collaboration of other interested brenchus of the e:my and the ravv. Inasmuch es it is appar mt that such studies must be made by mgms of large scele exporimontation, as well as laboratory research, it will be essential that thore available in some isojeted region on extensivo proving ground. _varioty of field trials could be conducted, the naturo of which in earlior discussions in this roport. be made Here a large are suggested). Le “To me, it would appear that the Chomical Warfare Servioe, in viow of its-long-standing experience in the use of other ohewioal and phys~ fenl agents of werfare, weuld be best adapted to undertake and supervise suoh @ program. .In addition, it weuld appear highly desirable to appoint & civilian edvisory committee oomposed of a group of chemists, physicists, eid men trained in the medical and biological sciences. This group of civ- flian scientists, which would presumably be drown from qualified individ= uals who have had extensive experience in the difforont aspects of tho recent developments in nuclear energy, would serve to assist and advise the armed forces whenever such help would ba needed. I believe that it would be imappropriate as well as difficult to sesk the assistance of universities for diroct research aid on most of the problems of investigation that the program indicated above would require. Lowevor, the fundamental lmowledge in the fields of chemistry, physios, end medicine that is in tho hands of the civilian scientists should be drawn upon fresly. . a - JOSEPH G.
