摘　　要：人工使用显微镜对蚀刻后的CR-39观测读数很容易产生视觉疲劳,自动分析读数的机器价格昂贵。该文介绍了日本弘前大学应急医学研究所采用的低成本解决方案:使用底片扫描仪或数码相机通过显微镜拍照的方式将蚀刻后的CR-39探测器表面图像数字化;对数字化后的图像用免费的ImageJ图像处理软件进行分析就可以完成对CR-39的自动读片。自动读片与人工读片的差异在可接受的范围之内。Manual observation and reading the number of tracks of etched CR-39 through microscope results in vision fatigue easily,automated analysis and reading machines are expensive.In this paper,we introduce a low-cost solution from the Institute of Emergency Medicine,Hirosaki University,Japan.Digital images of the etched CR-39 detectors surface can be obtained by a film scanner or a digital camera with a microscope.Automatic readings the tracks of CR-39 can be achieved through the analysis of digital images by free image processing software,ImageJ.The difference between the automatic and manual reading is in the acceptable range.
