| 内容記述 | The time-dependence of 137Cs in green tea following a 137Cs-deposition was analysed and quantified in terms of effective half-lives. The underlying monitoring studies were performed after the accidents in the Chernobyl and the Fukushima Daiichi nuclear power plants for tea plants growing in Japan. The major transfer route for 137Cs to the first new shoots after the accidents were different: for the Fukushima accident, it was mainly translocation of caesium deposited onto old leaves and twigs to the new growth, while direct deposition on the new shoots was the major source after the Chernobyl accident. The effective half-lives representing the fast and slow components of the decline did not significantly differ between these accidents. Geometric means (ranges) of fast and slow effective half-lives after the Chernobyl accident were 66 d (25 - 125 d) and 902 d (342 - 15900 d), respectively, and those after the Fukushima accident were 50 d (26 - 105 d) and 416 d (222- 1540 d), respectively. Because the absorption of radiocaesium from the contaminated surface of inner plant tissues does not continue for a long time, the initial contamination route of the plant is less important for long-term considerations. | |||||
