摘要
用高精度的核化学和放射化学方法研究了穆萨拉湖、阿列科湖和冰湖三个湖泊的地表水和穆萨拉山降水的氚含量。这些测量是保加利亚科学院核研究和核能研究所制定和维护的长期环境监测计划的一部分。在2012-2017年期间，在里拉的穆萨拉地区收集的湖水和降水样本的结果发现，其范围为小于1.20至2.77 Bq。L-1和2.14 ~ 4.12 Bq。l - 1。所有样品中3H的含量均低于100bq . l -1的推荐水平。所获得的新结果可用于评价所调查水源的辐射状况，并可用于评价未来可能的变化和趋势。
DISTRIBUTION OF TRITIUM IN SURFACE WATER AND PRECIPITATION IN RILA MOUNTAIN, BULGARIA
A study of the tritium content of surface water from three Rila lakes – Moussala lake, Aleko lake and Ice lake, and precipitation at Moussala mount has been performed by means of high precision nuclear and radiochemical methods. The measurements are part of a long-term environmental monitoring program developed and maintained by the Institute for Nuclear Research and Nuclear Energy, Bulgaria Academy of Science. The results for lake water and precipitation samples collected at Moussala part of Rila over the period 2012–2017 were found to range from ˂ 1.20 to 2.77 Bq.L-1 and from 2.14 to 4.12 Bq.L-1 respectively. The content of 3H in all samples is below the recommended level of 100 Bq.L-1.
The obtained new results are used to assess the radiation status of the investigated water sources and can be used for evaluation of possible future changes and trends.
