碩士 === 國立陽明大學 === 放射醫學科學研究所 === 90 === This research include two parts. First part is the dose reconstruction and evaluation for residents living in radiation contaminated buildings and compared the results of this study with those of the Atomic Energy Council and professor Tung Chuan-zhung. The comparison showed that the results of dose assessment of this study were close to professor Tung’s results. The second part is to discuss and derive the risk of radiation induced cancer mortalities at low dose rate exposure. The risk factor for residents living in radiation contaminated buildings were evaluated by extrapolation methods of population, time (additive model and multiplicative model) and dose based on the primary risk coefficient of Japanese A-bomb survivor. The derived risk factor is between 12.15 × 10-2Sv-1 and 0.55 × 10-2Sv-1.
