Feasibility study on a continuous environmental gamma-ray monitor using a NaI(Tl) scintillation spectrometer.
Energy spectra of gamma rays due to artificial radionuclides could be estimated by using a NaI(Tl) scintillation spectrometer on the basis of the analysis of natural environmental gamma rays. This analysis system was applied to a continuous gamma-ray monitor in the vicinity of a nuclear facility, and a plume exposure rate due to gaseous effluents of about 6 X 10(-2) Ci hr-1 (2.2 X 10(9) Bq hr-1) could be estimated successfully downwind from the stack.
