Abstract

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.

摘要

基于对天然环境伽马射线的分析，利用碘化钠（铊）闪烁光谱仪可以估算出由人工放射性核素产生的伽马射线能谱。该分析系统应用于核设施附近的连续伽马射线监测仪，成功估算出烟囱下风方向气态流出物导致的大约6×10⁻²居里·小时⁻¹（2.2×10⁹贝可勒尔·小时⁻¹）的羽流照射率。
