From 3rd Health Physics Society midyear topical symposium: Los Angeles, California, USA (29 Jan 1969). See CONF-690103P2. A research program at the Lawrence Radiation Laboratory, Livermore, involved handling of kilocurie quantities of /sup 147/Pm in the development of radioisotope power sources. A high-level plutonium laboratory was reorganized for this work. The low energy of the /sup 147/Pm BETA necessitated development of special techniques for continuous air monitoring and contamination control. An LRLdesigned air monitor and a shoe counter using large-area G. M. detectors are described. Assembly of the power sources involved delicate work which could not be done remotely. Hand exposures from bremsstrahlung and gamma -emitting impurities became the limiting health physics problem. Experiences in exposure and contamination control are discussed. (auth)
