摘要

FD-71闪烁辐射仪在天然本底调查和建筑材料卫生标准的研究等方面得到了较广泛的应用。从天然环境辐射测量的观点出发，曾报道过用FD-71测量天然环境辐射的读数修正方法和在不同的环境中与高压电离室、塑料闪烁辐射仪比对测量的结果

[1]

。本文将报道FD-71测量天然环境辐射场所具有的一些主要技术性能，包括探测下限、量程范围、均匀性、重复性、稳定性和对复杂环境条件的耐受能力等。本文的实验结果一般是利用环境辐射场得到的。仪器的刻度方法和读数修正公式均与文献[1]一致。

Abstract

FD-71 NaI(Tl) scintillation radiometer is a sensitive

simple and portable instrument. The characteristics for this radiometer are described in this paper.

The detection capability of FD-71 radiometer is 0.5—500 µRh

-1

for terrestrial gamma radiation. The differences of the readings between different instruments are generally within 5% and the differences in reproducibility and stability of different instruments are within 3% and 5%

respectively.
