氚水(HTO)在人体内的生物半衰期很短,为7到14天,这既减少了单次摄入事件的总影响,也排除了HTO从环境中长期生物积累的可能性。氚水在人体内的生物半衰期,作为衡量体水周转的指标,随季节而变化。对印度卡纳塔克邦沿海地区职业辐射工作者自由水氚的生物半衰期研究表明,冬季的生物半衰期是夏季的两倍。(维基百科)
Tritiated water (HTO) has a short biological half-life in the human body of 7 to 14 days, which both reduces the total effects of single-incident ingestion and precludes long-term bioaccumulation of HTO from the environment. Biological half life of tritiated water in human body, which is a measure of body water turn over, varies with season. Studies on biological half life of occupational radiation workers for free water tritium in the coastal region of Karnataka, India show that the biological half life in winter season is twice that of the summer season.
