Radiation Dose Reduction Efficiency of Buildings after the Accident at the Fukushima Daiichi Nuclear Power Station
Numerous radionuclides were released from the Fukushima Daiichi Nuclear Power Station (F1-NPS) in Japan following the magnitude 9.0 earthquake and tsunami on March 11, 2011. Local residents have been eager to calculate their individual radiation exposure. Thus, absorbed dose rates in the indoor and outdoor air at evacuation sites in the Fukushima Prefecture were measured using a gamma-ray measu...
متن کاملEstimation of β-ray dose in air and soil from Fukushima Daiichi Power Plant accident
Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident of 2011, which deposited radionuclides across Tohoku and northern Kanto, β-ray dose evaluation has been performed to estimate radiation exposure for small creatures like insects as well as human skin. Using the Monte Carlo radiation transport code MCNP-4C, we calculated the β-ray dose for (129m)Te, (129)Te, (131)I, (132)Te, (1...
متن کاملCurrent Research and Development Activities on Fission Products and Hydrogen Risk after the Accident at Fukushima Daiichi Nuclear Power Station
After the Fukushima Daiichi nuclear power plant (NPP) accident, new regulatory requirements were enforced in July 2013 and a backfit was required for all existing nuclear power plants. It is required to take measures to prevent severe accidents and mitigate their radiological consequences. The Regulatory Standard and Research Department, Secretariat of Nuclear Regulation Authority (S/NRA/R) has...
متن کاملPsychological distress of residents in Kawauchi village, Fukushima Prefecture after the accident at Fukushima Daiichi Nuclear Power Station: the Fukushima Health Management Survey
BACKGROUND To shed light on the mental health of evacuees after the accident at Fukushima Daiichi Nuclear Power Station (FDNPS), we evaluate the results of the Fukushima Health Management Survey (FHMS) of the residents at Kawauchi village in Fukushima, which is located less than 30 km from the FDNPS. METHODS We conducted the cross-sectional study within the framework of the FHMS. Exposure val...
متن کاملFukushima daiichi nuclear accident and radiation exposure.
We consider that the Great East Japan Earthquake was a combined disaster involving earthquake and tsunami as well as the release of radioactive materials into the environment (Fig. 1). Something I would like you to notice here is that among various disasters, a radiation nuclear disaster cannot be seen; it cannot be felt; in fact it cannot be detected without special devices. Because of that, t...
