摘要
测定了太阳、日光灯、紫外灯光源的光谱特性,确定了各种光源光照度随距离的变化关系。研究了辐射变色薄膜剂量计暴露于上述光源及室内自然光源下,单位厚度光密度变化与暴露时间的关系,说明了不同光源对响应影响的程度并指出了如何控制这类无法进行修正的影响因素。
There are several factors affecting the response of radiochromic dyedosimeters to ionizing radiation. Some of them are avoidable or controllable, butcan not be corrected in practice such as effect of light. Others are not avoidable orcontrollable, but can be corrected, such as effect of temperature. Spectral characteris-tics of incandescent light, daylight, UV-light and sunlight have been determined inthis paper. This is helpful for the explanation of the effect. The changes in illumi-nation of different light sources with distances are shown. The relationships betweenthe change in optical density per unit thickness and time of exposure to incandescentlight, daylight, UV-light, and sunlight have been measured. It comes to a conclusionthat radiochromic dye dosimeters are not so sensitive as photoplate film to visibleand incandescent light but the background and post-irradiation optical densities willbe rapidly increased when they are exposed to daylight, sunlight. or UV-light for awhile. Therefore, they should be kept or stored in dark places.
