Fukushima Dai-Ichi Nuclear Power Plant (located 200km northeast of University of Tsukuba S.H.S. at Sakado in Japan) had an accident due to huge tsunami with strong earthquake on  11-Mar-2011 offshore East Japan and radioisotopes were leaked to  environment.Radiation measurement of environment and students' bodies has been conducted by students at the school in June and October 2011. Increased amount of radiation was observed for 10/37 students' palms, chicken coop and one of ghilgai at the neighbor of club shacks during about four months from June to October 2011. The amount of largest variation for 17-year-old male student was 0.063 microsievert per hour (�Sv/h) on 06-June-2011 but 0.133 �Sv/h on 24-October-2011 and for 17-year-old female student was 0.035 �Sv/h on 06-June-2011 but 0.062 �Sv/h on 24-October-2011.These increased amount of radiation should be  affected by the accident of the nuclear power plant.
