【摘要】 对于异形物体表面的核辐射α污染监测,采用传统检测手段难以实现。LRAD(Long rangealpha detection)技术提供了一种测量表面α污染的新方法。通过该项技术可以检测手持探头扫描法无法检测到的不规则异性管道的表面污染情况。基于LRAD技术原理,研制出一种α表面污染报警仪样机。通过该样机,完成了相关实验测试及部分检验工作。更多还原

【Abstract】 It’s difficult to use the traditional monitor methods to detect the alpha contamination on the irregular object’s surface.The LRAD(Long range alpha detection) technique provides a new method to monitor the alpha surface contamination.By the technique can detect the surface contamination in the irregular tube where use the hand-held detector scan method can’t detect.Based on the LRAD technique principle,develop an alpha surface contamination meter.Using the alpha surface contamination meter,finished the correlation experiments and some examine works.更多还原
