The Health Control Policy of Japan was established in 1965 by the Atomic Energy Commission and has not been revised since then. However, in 1972, a law concerning the health of elderly persons was enacted, and the recommendations of the International Commission for Radiological Protection (ICRP), which presents the basic standards regarding radiation protection, were published. Both of these events had a very strong impact on the drafting of health control policy, as the Japanese Government was compelled to introduce a new policy aimed at reducing the risk of cancer, the greatest physical probability risk facing radiation workers. Laws governing the physical examinations of radiation workers working in nuclear power stations in Japan are divided into three groups: 1) Laws for Safety and Sanitary Conditions of Workers; 2) Laws for Health Insurance Cooperatives; and 3) Law for the Health of the Elderly. As controlling the data of these examinations is more complicated than that of the physical examinations of A-bomb survivors, a centralized registration system is needed. This paper proposes the need for such a registration system to be granted under the three laws governing special accounts for power supply municipalities and suggests setting up the system within regional medical information systems. It also proposes the founding of an overall health insurance cooperative, to be managed by the Contractors Safety Union in each municipality.

Management of radiation-induced risks in areas contaminated by a nuclear accident is characterized by three ethical issues: (i) risk trade-off, (ii) paternalistic intervention and (iii) individualization of responsibilities. To deal with these issues and to clarify requirements of justification of interventions for the purpose of reduction in radiation-induced risks, we explored the ethical basis of the radiological protection system of the International Commission on Radiological Protection (ICRP). The ICRP's radiological protection system is established based on three normative ethics, i.e. utilitarianism, deontology and virtue ethics. The three ethical issues can be resolved based on the decision-making framework which is constructed in combination with these ethical theories. In addition, the interventions for inhabitants have the possibility to be justified in accordance with two ways. Firstly, when the dangers are severe and far-reaching, interventions could be justified with a sufficient explanation about the nature of harmful effects (or beneficial consequences). Secondly, if autonomy of intervened-individuals can be promoted, those interventions could be justified.

Strategic research will be needed to unveil the uncertainty regarding the health effect of radiation at low dose and low dose rate. Recently, the National Council on Radiation Protection and Measurements (NCRP) published Commentary No. 24 dealing with the perspective of integrating radiation biology and epidemiology to address this issue. Results of radiation biology have not been effectively used for radiation risk assessment because 1) available epidemiological studies based on direct observation of human population have been considered to be the most relevant despite their uncertainties and 2) biological studies have not been conducted with their use in risk assessment in mind. The present paper summarizes the Commentary to present perspectives on integrating biology and epidemiology for radiation risk assessment.

For the purpose of utilizing radiation-induced chromosome aberrations in human peripheral blood lymphocytes as a means of dose evaluation in a criticality accident, a study was made of the relationship between fission neutron+gamma dose and the chromosome aberrations. Human peripheral blood lymphocytes were exposed in vitro to fission neutrons+gamma rays at Japan Research Reactor No. 4 for 5, 10, 20, 30, or 40min at 200kW. The cells were observed at their first mitotic division stage in culture.The frequency of the chromosome aberrations per cell, Y, was expressed as a power function of exposure time in minutes, t, as follows: Y=0.0018t1.12.On the assumption that there was no mutual interaction between chromosome aberrations induced by the neutrons and those by gamma rays and that there was similarity of the effects of the gamma rays produced in fissions and those of Co-60 gamma ays, estimation was made of contribution of the gamma rays to total yields. However, there was a contradiction that the contribution of gamma rays exceeded the total yield.

As part of the environmental radiation monitoring around the nuclear fuel cycle facilities constructed in Rokkasho-mura, we are carrying out continuous measurements of gross α and gross β radioactivities in air dust samples. Considering there measuring conditions, it is suggested that 210Po and 210Bi mainly contribute to gross α and gross β, respectively. The higher concentration of gross β radioactivity was observed during fall and winter. But then gross α radioactivity lowered during winter, and fluctuated on spring and fall. It is suggested that surface soils are one of major origins of gross α radioactivity, because 210Po/210Pb ratio in the soil is higher than the ratio in the air and the ground is covered with snow in winter. Large peaks of gross a radioactivity and α/β radioactivity ratio were observed on May 2003. Satellite imageries showed forest fires around Lake Baikal in this period. We confirmed that the air mass passed the vicinity of Lake Baikal and flowed in Rokkasho-mura by backward trajectories. There was a positive correlation between gross α radioactivity and the frequency of air mass traveling from the vicinity of Lake Baikal to Rokkasho-mura. The result suggested that the large peaks of the concentration of gross α radioactivity and α/β radioactivity ratio were caused by the forest fire in Russia.

Ambient dose rates are continuously monitored in Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency. The present study discussed the variations in ambient dose rates, observed from April 2014 to March 2015, due to snowfall as well as rainfall. It is much snowy as one of climatic features in this area. Rain or snow was sampled for a certain period in the day of interest (17 cases in total), and then the concentration of radon progeny was measured. With the measured data, the variation in ambient dose rate was calculated considering the accumulation of the radon progeny on the ground. As a whole, this calculation was found to reasonably reproduce the time trends of observed dose rates, except for four cases. Based on the backward trajectory analysis, it was explained that the discrepancy in two cases out of the four was induced by changes of radon progeny concentration in precipitation around sampling period. It was suggested that the other two cases were caused by the run-off of rain from the ground surface.
