Information furnished FCDA and -NSRB. ‘The’ Acting Deputy Admintstrator, FCDA, and the Director, - Health Resources Office, NSRBJ have been furnished a ‘statement of levels of: radioactive contamination jn water’: and food permissible under emergency comiitions.: ‘This ‘statemnt.was. prepared for use of the AEC emergency radiation monitoring teams in event of atomic disaster ‘and was furnished these agencies: for use if their national civil defense program. . Review of FCDA documents. FCDA's "Health Services andj Special Weapons Defense" Manual was further reviewed for technical ackuracy in galley-proof and page-proof form prior to its public release fon December 27, 1950. Radiation Instruments Branch The FCDA issued Specifications for Civil Defense Radiblogical Monitoring Instruments on December 6, 1950, as the result offinitial broad specifications prepared by the Radiation Instruments anch. Al- though there are several points in the issued specification with which AEC persons are not in complete agreement, the specificatiozs will be useful to radiation instrument manufacturers in giving them ffirm opera- It is pro ‘ tional characteristics to which they can design instruments] posed that resulting prototype instruments will be evaluated by the National Bureau of Standards. Procurement and Industrial Development Activities AkC-sponsored research and development. Twenty of the civil defense radiation monitors manufactured by the Victoreen Instfument Company under AEC contract were received during December. These instruments are of the ionization chamber type employing the DuBridge-Browy electrometer circuit. The upper range of these instruments is 25 roentgens per hour. No determination has been made of the spectral and performdmce characteristics of these instruments. . Inspection and testing. During the month of Decemb@r, 180 radiation detection instruments, accessories, and components wefe received ‘and tested. Seventy-five neutron dosimeters produced by the Cambridge Instrument Company were rejected beeause of manufacturing Hlefects. Since these dosimeters were procured under a production developypnt contract supervised by the NYO Instruments Branch, they will be rethhrned to their Laboratory for further inspection and return to the manufacturer. Technical Coordination Activities Military activities in radiation instrumentation. Progress repcerts concerning the many military administered contracts irvolping research in radiation detection have not received sufficient distribufion within the AEC. Since it would be difficult to obtain the number off copies to make a complete distribution, the Branch is planning to abstrabt and disseminate this information directiy.
