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氧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±３．４Ｂｑ·ｍ￣（－３），和后期告知的标准氧暴露量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。
An image processing solid statenuclear detector (SSNTD ) for radonsuryey has been deyeloped by usingcomputer technique of image discrim-mation' The method had good accuracy, i, e', the Rn concentration(106'8 t 3 '4 kBq .m- s .h ) determinedby this detector was in good accordance with the giyen exposure Yalue(115' 6 t 3' 4 kBq.m- s .h), and greatly increased measurement speed.It has been widely used in Rn inyestigation in hundreds of devillingsand galleries'
