AEC-Sponsored Research and Development Requirements for large additional quantities of enriched boron-lined neutron counters for the Santa Fe Cperations Office have stimulated reconsideration of the need for an alternate producer of these components for the ABC. The existing contract for the supply of these tubes let with the General Slectric Company is being administered by the NY¥CO. Thus far, five companies, i.e., Raytheon Manufacturing Company, Federal TeleCommunications Laboratories, Rauland Manufacturing Company, Allan 3. Dumont Laboratories and Radiation Co:nter Laboratories, have been or will be extended an opportunity to participate in this work. The Instruments Sranch of the NYOO Health and Safety Division will continue to furnish technical supervision for this program. Civil Defense Training Two shipments, totaling 32 survey meters, were made during the month for civil defense trainings purposes. Twelve of the instruments were loaned to the jtate of Alabama for a two-monty period with training to be under the supervision of Dr. Bric Rodgers of the University of Alabama. Twenty instruments were loaned to California for three weeks with training to be directed by the University of California. RA-~DET The May issue of RA-DET will feature a report by B. Cassen and others at the Berkeley Radiation Laboratory on scintillation counting equipment for medical usage. This month's biographical sketch is of P. R. Sell of Oak Ridge National Laboratory, The first progress report of work performed by RCA under the Special Tube Development Contract. will also appear in this issue. It is planned to disseminate information —________._____onRCA's work by sublishing all future progress reports in RA-DET. OFFICE » Po 16—55741-1
