| Outline of Final Research Achievements |
We compared liver damage by radiation with by alcohol which is living environment factor to dispel the fear of low-dose radiation. We analyzed liver function and anti-oxidative function in liver using self-organizing maps. The results showed that the effects of radon inhalation at a concentration of up to 2000 Bq/m3 or X-irradiation at a dose of up to 2.0 Gy were comparable with the effect of alcohol administration at 0.5 g/kg bodyweight. According to our result of clustering, their different patterns of liver damage caused by different factors. We found that the effects of low-dose X-irradiation or radon inhalation was extremely small and highly individual.
