在高剂量测量中辐射变色薄膜剂量计既可用于常规测量又可作为传递剂量计,还可用作辐照产品的标签,因而得到了广泛的应用。尽管它不像胶片剂量计那样对光十分敏感,但是暴露在某些波长范围的光辐射下会对本底或照后光密度产生明显的影响。这方面的工作过去未见系统定量的报道。本工作的研究内容、特点和结果归纳如下: Radiochromic membrane dosimeters are widely used in both high-dose measurement and routine measurement as well as delivery dosimeters and as labels for irradiated products. Although it is not as sensitive to light as film dosimeters, exposure to light radiation in certain wavelength ranges can have a significant effect on the background or after-photo density. In the past, there was no systematic and quantitative report on this work. The research content, characteristics and results of this work are summarized as follows:
