摘要
CR-39固体径迹探测器因其材料的稳定性、良好的实用性等特点被广泛应用于氡的测量领域。针对现有的商用固体径迹探测器自动测读系统价格昂贵、维护成本及环境要求高的问题,本研究利用平板扫描仪设备,开展固体径迹形态学研究,通过建立基于径迹形态学参数的氡径迹识别法则,实现氡的高效、低成本测量。测量结果表明氡暴露量在500 kBq·h/m^(3)以下时,径迹密度-暴露量曲线呈现良好的线性关系。研究表明,基于平板扫描仪的氡测量方法有望实现氡的高效测量且该测读方法兼顾高效、低成本、环境适应性强的特点。
CR-39 solid track detector is widely used in radon measurement because of its material stability and good practicability.In view of the high cost,maintenance cost and high environmental requirements of the existing commercial automatic reading system for solid track detectors,this study uses flatbed scanner equipment to carry out the study of solid track morphology,and establishes the radon track recognition rule based on track morphology parameters to achieve high efficiency and low cost radon measurement.The measured results show that the track density-exposure curve presents a good linear relationship when the radon exposure is below 500 kBq·h/m^(3).The research shows that the radon measurement method based on flatbed scanner is expected to achieve high efficiency measurement of radon,and the characteristics of this measurement method are high efficiency,low cost and strong environmental adaptability.
