辐射径迹测量中的荧光激发影像板技术

Imaging Plate Technology Used in Measurement of Irradiation Tracks

文章利用理论模拟计算手段研究荧光激发影像板(IP)对辐射径迹的响应。计算显示,IP对各种辐射径迹的灵敏度关系为:α径迹>β径迹>γ径迹。实验验证了理论模拟计算结果的可靠性,探讨了在α、β、γ射线混合场中IP测量单一射线的可行性、干扰及其消除方法,并介绍了IP技术在放射性污染植物修复研究中的应用状况。

The imaging plat （IP） responsivity to irradiation tracks was theoretically studied in the present work. The results show that the IP responsivity to different irradiation tracks has the following relationship, α track β track γ track. The theoretical calculation is experimentally proved to be reliable. The possibility to measure only one kind of tracks in a mixed irradiation field （α, β and γ-ray）, interference of one to another and shielding method were explored. The IP technology used in the field of phytoremediation of radionuclide contaminated soil was introduced.
