7、91Y射线水吸收剂量标准剂量计(辐射加工级)检定规程本规程适用于用国家吸收剂量基准硫酸亚铁(Fricke)剂量计,在水模体中,以替代法检定新制造、使用中和修理后的辐射加工级水吸收剂量标准剂量计。检定在MC.或137Cs7射线的辐射场中进行。用标准剂量计检定工作剂量计时,其检定方法可参照本规程进行。一概述标准剂量计是指经过考核的,测量水吸收剂量的总不确定度小于3%一4%(k=2),能用于辐射加工级水吸收剂量量值传递,在辐射加工现场测量吸收剂量和校准工作剂量计的剂量测量体系。标准剂量计包括液体(化学)剂量计、固体剂量计和电离室剂量计。
8、液体剂量计如硫酸亚铁剂量计、重铬酸钾(银)剂量计、重铬酸银剂量计和硫酸柿一亚饰剂量计等。它们是由密封于玻璃安瓶中的剂量计溶液和UV/vis分光光度计组成。在电离辐射作用下,剂量计溶液中的溶质离子被水的辐解产物定量地氧化或还原;用分光光度计在一定波长
