广东省环境水体中的氚活度浓度水平

Abstract

Abstract: Tritium activity concentration levels in environmental water in Guangdong Province were surveyed between 2012 and 2013. The results showed that: (1) Tritium activity concentration levels of water vapor in the air, river water, and reservoir water were significantly higher than those in sea water and ground water (p＜0.01). Tritium activity concentration level of water vapor in the air was higher than that of rainfall (p＜0.05); (2) Tritium activity concentration levels of river water and rainfall correlated with that of water vapor in the air (The Pearson correlation coefficients were 0.655 and 0.637, respectively; p＜0.01). Tritium activity concentration levels of reservoir water and river water were also affected by rainfall (The Pearson correlation coefficients were 0.444 and 0.440, respectively; p＜0.1); (3) The survey results were consistent with historical data. The present tritium activity concentration levels in environmental water in Guangdong Province ranged from 0.081 to 0.69 Bq/L, which are close to pre-bomb levels; (4) Tritium activity concentration levels in environmental water around Daya Bay and Ling'ao nuclear power plants were about 5 to10 times higher than the rest of Guangdong Province.

Key words: Guangdong Province, environmental water, tritium
