摘要

核燃料后处理厂向海洋释放多种放射性核素，主要是 3H 和 129I。放射性碘会导致甲状腺中毒。碘会在裙带菜和鲍鱼等几种海洋生物体内蓄积，而裙带菜和鲍鱼都是食用材料。因此，分析碘在海洋环境中的行为对于评估 129I 的影响非常重要。海水中的碘主要以两种化学形式存在：碘化物（I-）和碘酸根（IO3-）。它们的环境行为各不相同。因此，了解这些行为对于评估总碘的环境行为非常重要。本研究用 125I 示踪剂观察了碘酸根和碘化物在海水和鲍鱼（Haliotis discus hannai）之间的转移。

Chemical form dependent iodine transfer from seawater into seaweed and abalone.

Nuclear fuel reprocessing plant releases several kinds of radioactive nuclides, mainly 3H and 129I, into the oceans. Radio iodine causes thyroid dose. Iodine accumulates in several marine species such as wakame and abalone, which are food materials. Therefore, an analysis of iodine behavior in the marine environment is important to assess the impact of 129I. Iodine in seawater exists mainly in two chemical forms: iodide (I-) and iodate (IO3-). Their environmental behaviors are different. Thus, understanding these behaviors is important to assess the environmental behavior of total iodine. In this study, iodate and iodide transfer between seawater and abalone (Haliotis discus hannai) with 125I tracer was observed.

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
