Abstract
Recently, it was recognized the importance to estimation impacts of radiation about non-human biota. ICRP reported estimation methods for non- human biota dose in ICRP Publication 108. On the other hand, ambient dose was broadly measured and reported after the nuclear accident because the measurement of ambient dose is easier than the measurement of radioactivity about each radionuclides. Some studies were estimated the radiation effects of non-human biota using ambient dose, however, ambient dose could not directly apply to the estimation of non-human biota.
In this study, the ambient dose to biota absorbed dose conversion factors for ICRP reference terrestrial organisms were calculated and we assessed environmental effect for the case in Fukushima Daiichi power plant accident.
