摘要
本文介绍了一种新的、多用途便携式α辐射仪,其探测器是常压空气脉冲电离室,仪器既可作常规射气测量,又可开展累积法测氡(α杯法,α卡法等),还能在野外现场作活性炭α测量,并有效地解决了探测器上放射性污染的去污处理问题.探测器灵敏面积500 cm^2,灵敏度高.数据采集及处理系统由PC-1500袖珍计算机构成,功能强.
A new type of portable instrument for measuring soil radon gas and its decay products has been developed and tested. A pulse-ionization chamber, filled with air at ordinary pressure, is designed as the detector of the instrument, which is easy to decontaminate and has the advantages of a large detecting area, simplicity of construction and low cost. The data acquisition and processing system is computerized (pocket computer PC-1500). The instrument can be applied for both integrated and instantaneous radon measurements.
