| Research Abstract |
Studies on the expoure caused by some natural radiation sources have carried out in order to Provide a quantitative basic for Public exposure.
(1) Exposure to radon in the living enving environments. ・The estimation of effective dose due to radon progeny. ・Exposure and protection to indoor radon.
(2) Exposure by operation of jet air crafts.
(3) Exposure by space flights.
(4) Exposure to materials containing signiticant traces of natural radionuclides. ・Irradation dose from radionuclides in foods. ・Radioelements in cigarette and its potential risk.
