CR-39固体探测器蚀刻后径迹分析和影响因素分析

Track analysis and influencing factors analysis on CR-39 solid state detector after etching

中子或者氡照射CR-39固体探测器后,其能量产生衰减,并在CR-39上产生了径迹,利用化学蚀刻等方法使其径迹得到放大,然后用现代显微镜技术可以进行观察和分析.CR-39广泛地应用于石油勘探人员的个人剂量监测、加速器放射治疗领域医务人员和患者的辐射防护监测、生活环境中氡含量的测量等方面.该文重点对CR-39固体探测器经化学蚀刻后的径迹及影响因素进行分析和介绍.

When neutron or radon irradiates CR-39 solid state detector,the energy is attenuated,and generating a track on the CR-39,which can be amplified by chemical etching and observed or analyzed by modern microscope.CR-39 is widely used in personal dose monitoring of oil exploration workers,radiation dose monitoring of medical staff and patients in the field of radiation therapy with accelerator and radon levels measurements in the living environments,etc.This article focuses on the CR-39 solid state detector track by chemical etching and the influencing factors are analyzed and introduced.
