摘要

发生核应急事件时需进行核辐射体内污染检测。针对大批量人群核辐射体内污染快速检测要求，研制了一款可同时完成α和γ放射性检测的一体机。该系统基于数字化能谱处理技术，利用离子注入表面钝化硅半导体（Planar Implanted Passivated Silicon，PIPS）探测器和NaI（Tl）探测器分别实现人体内α、γ射线测量。测试结果表明，仪器对

239

Pu的能量分辨率为6.1%，对

137

Cs的能量分辨率为6.9%。该系统能够以每小时大于等于10人次的速率实现检测，满足内污染快速检测要求，能够为后续诊断提供可靠依据。

Abstract

Background

It is necessary to detect internal contamination when nuclear emergency events happened.

Purpose

This study aims to develop an instrument to fast detect internal radiation contamination of large crowds.

Methods

An integrated machine capable of simultaneous detection of α and γ radiation was developed. Based on the digital energy spectrum processing technology

α-ray from nose swab is detected by using planar implanted passivated silicon (PIPS) whilst the NaI (Tl) detector is equipped to measure the γ-ray which deposits in lung of human body.

Results

The experimental testing results show that the energy resolution of the instrument is 6.1% for

239

Pu and 6.9% for

137

Cs. The processing speed is no less than 10 persons per hour.

Conclusion

Detection speed and the energy resolution of proposed instrument satisfy the requirement of fast measuring internal radiation contamination of large crowds. It can provide reliable evidence for subsequent diagnosis.
