Outline of Final Research Achievements	Radiation risks have been evaluated basically from the Hiroshima and Nagasaki studies. After the discussion at International Commission on Radiological Protection (ICRP), the risks have been prescribed by the Japanese law of radiation protection. The radiations of the atomic bombs were exposure of the moment. However, that of the Semipalatinsk was long time exposure. Therefore we considered their radiation risks are different and began this project. The studies were radiation dosimetry and risk analysis based on international collaboration. Our measurements and results obtained were 1. Cs-137 and Pu isotopes in soil samples, 2. radiation doses using bricks, tooth enamel and chromosome aberration of blood, 3. psychological effects by hearings form residents, 4. maintenance of the data base and risk evaluation and 5. animal experiment of microparticle effects. From these studies we elucidated the radiation doses and realities of exposures what was happened in Semipalatinsk.
