对 1987 年 4 月至 1991 年 7 月在日本福冈收集的雨水中的氚浓度进行了测量。每次“雨”的氚浓度变化较大，范围为0.06~3.39 Bq 1−1，平均值为0.62 Bq 1−1。天气条件显着影响雨中氚浓度。当气团主要从亚洲大陆移动到福冈时，观察到较高的氚浓度。 1987年以后福冈年平均浓度不再下降。
Tritium concentrations in rain water collected in Fukuoka, Japan, from April 1987 to July 1991, were measured. The tritium concentration of each ‘rain’ showed a large variation from 0.06–3.39 Bq 1−1, with an average value of 0.62 Bq 1−1. Weather conditions significantly affected the tritium concentration in rain. Higher tritium concentrations were observed when air-mass moved dominantly from the Asian Continent to Fukuoka. The annual average concentrations were no longer decreased after 1987 in Fukuoka.
