Description: An instrument has been built to survey releases of radioactivity within the 22-acre enclosure of the Savannah River Laboratory. The device consists of a 2-in.diameter x 2-in. sodium iodide scintillation crystal with associated detector counting and recording circuits which provide a permanent record of radioactivity movements within the Laboratory area. The monitor detects signals of 6.9 mu r/hr from a 0.48-curie cobalt-60 source located 265 ft away. (auth)
