Outline of Final Research Achievements

In order to construct the estimation method for the effect of tritium (T) derived from nuclear power plants on the human body, the hydrogen isotope exchange reaction (the T-for-H exchange reaction) between each amino acid (or each organic compound) and HTO was observed at several temperatures and several prescribed times. Moreover, after the accident of Fukushima Daiichi Nuclear Plants, some waters in lakes around Fukushima prefecture and Niigata city were analyzed.
As the results, T in HTO was incorporated into human body as Organic Bonded T etc. It is found that considering the T-for-H exchange reaction, the effect of the exchange reaction to human body is slightly larger than the result obtained from the current method, and that the estimation method in this work is useful to calculate the Radiation Weighting Coefficient. It is also found that the effects of the accident on Niigata city is so small.
