The large Japanese field mouse (Apodemus speciosus) which endemic wild mice living in Japanese forest, was monitored after the Fukushima nuclear power plant released a large amount of radioactive materials due to accident. We will introduce current status of radiocesium contamination, estimated radiation dose, and effect in the field mouse. According to calculation of radiation dose using Monte Carlo electron-photon transport code EGS5, it was clarified that dose rate level of the field mouse fall under derived consideration reference level determined by ICRP. Analysis of the oxidative stress in male mice testis revealed the damage in testicular cells of mice collected in 2012, when monitoring began.
