摘要

伽马照相机是一种有用的测量仪器，可以掌握污染物的分布情况，但对污染物的放射性估计是困难的。如果用针孔伽马照相机测量γ射线的总能量吸收峰计数率，我们应该能够估计放射性。利用源与测量点之间的距离和直接γ射线的峰值计数率可以解析计算。采用日立公司的HDG-E1500型针孔伽马相机，研究了Cs放射性的估算方法，该方法可用于测量γ射线的总能量吸收峰计数率。

Measurement of 137Cs Activity with Pinhole Gamma Camera

The gamma camera is a useful measuring device for grasping the distribution of contamination, but estimating the radioactivity of contamination is difficult. If the total energy absorption peak count rate of γ-rays can be measured with a pinhole gamma camera, we should be able to estimate the radioactivity. We can calculate it analytically by using the distance between the source and measurement points, and the peak count rate of direct γ-rays. The estimation method of Cs radioactivity using a pinhole gamma camera was studied using Hitachi’s gamma camera (HDG-E1500), which can be used to measure the total energy absorption peak count rate of γ-rays.
