本文介绍了一种简便的成像板系统，用于放射性铯污染土壤的放射性检测。用薄聚乙烯膜真空密封一组两个IP条，以防止IP条直接接触土壤和被润湿。在放射性土壤的检查中，将包括该IP条监测器的不锈钢管放入地下，然后将其从地下拔出后保存在铅容器中，以减少周围的伽马射线背景。此外，还制作了一个灵敏的读数器，通过激光束在IP条上的扫描来测量光致发光。通过对实际放射性铯污染土壤的实验，证实了带读数器的IP条监测器能有效地检测放射性铯的β射线，可满意地用于放射性土壤的检测。
A simple and convenient system with imaging plates (IPs) was well constructed for the radioactivity examination of soil contaminated with radioactive caesium. A set of two IP strips was vacuum-sealed with thin polyethylene film to prevent the IP strips from direct contacting soil and from being moisturized. In the examination of radioactive soil, a stainless steel pipe including this IP strip monitor was put into the ground and then it was kept in a lead container after being pulled out of the ground for the reduction of the surrounding gamma-ray background. In addition, a sensitive reader was well made for the measurement of the photostimulated luminescence through the scanning of a laser beam on the IP strip. It was confirmed from experiments on actual radioactive-caesium-contaminated soil that the IP strip monitor with the reader effectively detected beta-rays from radioactive caesium and could be satisfactorily used for the examination of radioactive soil.
