换一批摘要作者利用计算机图像识别技术，建立了测量环境空气中氡浓度测定的固体径迹图像分析方法，并在营房、坑道的氡水平调查中得到了应用。该方法与国家二级计量站标准氡室的比对结果为106.8士3.4Bq·m -8和后期告知的标准氡暴露量115·6±4.3Bq·m -3，相对误差约为7.6%。测量速度较显微镜目测法有很大的提高，适合环境空气中氡浓度的测定和大规模氡水平调查。

abstractsAn image processing solid state nuclear detector (SSNTD) for radon survey has been developed by using computer technique of image discrimination. The method had good accuracy, i, e., the Rn concentration (106.8±3.4 kBq·m -3·h) determined by this detector was in good accordance with the given exposure value (115.6±3.4 kBq·m -3·h), and greatly increased measurement speed. It has been widely used in Rn investigation in hundreds of dwellings and galleries.
