NaCl is a cheap and widely available material. This study investigated the potential of NaCl in the form of a household salt as a retrospective and accident dosemeter using optically stimulated luminescence (OSL). Samples of the investigated household salt were stimulated using blue light of linearly modulated power. Attention was concentrated on sensitivity, dose dependence of the OSL signal, fading, optimisation of the read-out procedure and application of analytical protocols that do not require a specific calibration. A potential of NaCl as a complementary dosemeter within emergency preparedness was considered. The behaviour of the OSL signal observed was found to be favourable for dosimetry.
氯化钠是一种廉价且广泛可得的材料。本研究调查了家用盐形式的氯化钠作为回顾性和事故剂量计使用光激发发光（OSL）的潜力。使用线性调制功率的蓝光对所研究的家用盐样品进行激发。注意力集中在灵敏度、OSL信号的剂量依赖性、衰退、读出程序的优化以及不需要特定校准的分析协议的应用上。考虑了氯化钠作为应急准备中补充剂量计的潜力。所观察到的OSL信号行为被发现有利于剂量测定。
