| 内容記述 | Social concerns for potential radiation risks due to nuclear power plant (NPP) routine operation have challenged us to overcome the inherent limitation of a geographical correlation study. A multi-site study to evaluate health risks in the NPP vicinities for a long time is useful to offer more comprehensive information than a local site study because the radiation dose is very small, at most 10-20 microsievert per year in Japan. Mortality rates from solid cancers and congenital anomalies (age<1 year) between 1972- 1997 in 100 selected Japanese municipalities either with or without a NPP were analyzed using Poisson regression. Excess relative risk (ERR) in all periods and 20 municipalities with a NPP showed a significant negative value (-0.052, P<0.001) for solid cancers and no significant different for congenital anomalies compared with in the remaining 80 control areas. Broadly speaking, the mortality rates from these two causes do not support the social concern about a possibly increased health risks due to radiation from Japanese NPP facilities although several issues remain to be resolved. At present it is not possible in the analysis for us to get an appropriate surrogate score for radiation dose. Further examinations are expected especially for specific site of groups of solid cancers. Our previous report observed a significant small positive ERR (0.228, p=0.0027) for leukemia mortality at old ages, which is due to factors other than radiation. On the other hand, a possible pathogenesis for congenital anomalies is less justified than for solid cancers; no adverse deterministic effects on fetus in the concerned radiation dose range and much less likely adverse genetic efffects than had worried in the past when conducting many tests of nuclear weapons in the atmosphere. Temporal and geographical pattern of these mortality rates throughout Japan will be useful to reduce uncertainty of our findings. |
