In order to clarify the radiation effects of the Fukushima Daiichi Nuclear Power Plant accident on living organisms, it is important to estimate the radiation dose to individual organisms. We have focused on carbonate radicals that induced in tooth enamel due to radiation, and have estimated the dose by using electron spin resonance technique. In this presentation, we report the results of dose response of radiation-induced radicals and the application of this method to low-dose area by using tooth enamel of Japanese macaque and hydroxyapatite.
