摘要

东京电力公司（TEPCO）开始向太平洋释放氚水。为了减少氚释放造成的不合理谣言，比目鱼、鲍鱼和沙参暴露在富含氚的海水中，并测量了与时间相关的组织自由水氚（TFWT）浓度。估算有机结合氚（OBT）的浓度对于评估氚的影响非常重要，因为它的生物半衰期比 TFWT 长。目前的模型使用 TFWT 浓度来估算 OBT 浓度。了解平衡时间对于准确预测 TFWT 浓度至关重要。TFWT 摄入率是通过分区模型进行分析的。

Tritium transfer from seawater into marine organisms TFWT.

Tokyo Electric Power Company, TEPCO, has started tritiated water release into the Pacific Ocean. In order to reduce unreasonable rumor caused by tritium release, flounder, abalone, and sarggasum were exposed to tritium enriched seawater, and time dependent Tissues Free Water Tritium (TFWT) concentration was measured. Estimating the concentration of Organically Bound Tritium (OBT) is important to assess tritium impact because it has a longer biological half-life than TFWT. Current models estimate OBT concentrations using TFWT concentration. Understanding equilibration time is critical for making accurate TFWT concentration predictions. TFWT intake rate was analysed by the compartment model.

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.
