摘要/Abstract

摘要： 针对水中放射性就地测量设备的效率刻度问题,提出一种用点源替代液体源进行效率刻度的方法。通过蒙卡计算,分别得到溴化镧探测器对点源和体源的光电峰计数概率,并建立起点源与体源效率刻度的对应关系,以便于在实际应用中简化水中放射性监测设备的效率刻度。

关键词: 水中放射性, 溴化镧探测器, 效率刻度

Abstract: To address the problems in efficiencycalibration of in-situ radioactivity measuring equipment, an approach to efficiency calibration was presented using point source in lieu of liquid volume source. Through Monte Carlo calculation, photoelectric count efficiency of lanthanumbromide detector to point and volume sources are obtained respectively and the relationship of calibration efficiency were established between point and volumesources for simplified use of efficiency calibration in practice.

Key words: Radioactivity in water, Lanthanum bromide detector, Efficiency calibration
