Five different types of instruments are being procured at a total cost of $20,160. Delivery of twenty models of each type is scheduled prior to January 1, 1951. $41,000 has been allotted to the Oak Ridge Operations Office for use by the Cak Ridge National Laboratory in financing a contract with the Raytheon -lanufacturing Company for production engineering of a pocketsized survey meter. This contract will be divided into two separate phases - the improvement of presently available electrometer tubes and the design of an instrument proper. This instrument will be sensitive to alpha, beta, and gamma radiation and will be calibrated from 1/100 to 100 roenteens per hour with an indication accuracy in the order of plus or minus 15 to 40 percent. Development at the other Commission sites is continuing. Contracts are being negotiated by both Brookhaven and New York for instrument component development. $56,000 was allotted to the Naval Radiological Defense Laboratory for a feasibility investigation of three additional types of radiological monitors. Le A standard operating procedure for the Washington, D, C, area emergency monitorine team has been preparedtand is to be discussed during a meeting of the team member sonJuly-105-1050..-.The team is-comprised of a ‘staff group and four sitordinatégroups 9srecruited from sfecific geographical locations, ineluding -lontgomery County, Arlington County, Prince Georges County, and the District of Columbia. A conference on reactor instrumentation was held under the joint sponsorship of the Radiation Instruments Branch and the Atomic Power Divi- sion of the Westinghouse Electric Corporation at Pittsburgh on June 5 and 6, The conference, being the first scheduled on this type of in- strumentation, was very successful in disseminating information and resolving various reactor instrumentation problems. The Agenda for the joint AHC-Department of Defense sponsored symposium on "Chemistry and Physics of Radiation Vosimetry" was reviewed by the Branch. The conference which is scheduled for September 18, 19, and 20 is very comprehensive and should be of considerable value to both yb organizations. ORGSLATIN & MANAEMENT 4 - DO®ARCHIVES
