Abstract

This study aimed to measure tritium (3H) concentrations in Thailand. Nationwide tap water samples were collected in July 2021. Rainwater samples were collected monthly during May-October 2020, April-October 2021, and February-March 2022 in Chonburi province and in Chiang Mai province during July-November 2021, January 2022, and March-June 2022. The measurements of 3H activity concentrations were conducted by Osaka Sangyo University (OSU) and were compared with measurements by the Thailand Institute of Nuclear Technology (TINT). The results from OSU and TINT showed that 3H concentrations in tap water were matched in the ranged from 0.08 ± 0.03 to 0.28 ± 0.04 Bq L-1, while those in rainwater samples collected from Chonburi province and Chiang Mai province are also matched in the ranged from 0.11 ± 0.02 to 0.21 ± 0.03 Bq L-1 and 0.19 ± 0.02 to 0.57 ± 0.04 Bq L-1, respectively. Our measured result suggests that 3H concentration in tap water and rainwater shows a similar relation depending on latitude.

监测泰国收集的自来水和雨水中的氚浓度。

本研究旨在测量泰国的氚（3H）浓度。2021 年 7 月采集了全国自来水样本。春武里府在 2020 年 5 月至 10 月、2021 年 4 月至 10 月和 2022 年 2 月至 3 月期间，清迈府在 2021 年 7 月至 11 月、2022 年 1 月和 2022 年 3 月至 6 月期间，每月收集雨水样本。3H 放射性活度浓度的测量由大阪产业大学（OSU）进行，并与泰国核技术研究所（TINT）的测量结果进行了比较。大阪产业大学和泰国核技术研究所的测量结果显示，自来水中的 3H 浓度在 0.08 ± 0.03 至 0.28 ± 0.04 Bq L-1 之间相符，而从春武里府和清迈府采集的雨水样本中的 3H 浓度也在 0.11 ± 0.02 至 0.21 ± 0.03 Bq L-1 和 0.19 ± 0.02 至 0.57 ± 0.04 Bq L-1 之间相符。我们的测量结果表明，自来水和雨水中的 3H 浓度与纬度有着相似的关系。

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.
