总结了日本最近对水样（雨水、沿海海水、湖水等）、大气样品（水蒸气、氢气和碳氢化合物）和松针（组织水和组织）的各种化学形式的环境氚水平的测量。讨论了日本不同自然水体中氚含量的差异和变化与水文和气象条件的关系。来自核设施的氚的明确证据来自松针的活动。讨论了在一般环境条件下土壤快速氧化氚化氢气的普遍现象。
Recent measurements of environmental tritium levels of various chemical forms in Japan are summarized for water samples (rain, coastal seawater, lake water, etc.), atmospheric samples (water vapor, hydrogen gas and hydrocarbons) and pine needles (tissue water and tissue). Differences and variation of tritium levels in various natural waters are discussed in relation to hydrological and meteorological conditions in Japan. Clear evidence of tritium originating from nuclear facilities is obtained from pine needles activity. Rapid oxidation of tritiated hydrogen gas by soils, a common phenomenon under general environmental conditions, is discussed.
