Thyroid doses for evacuees from the Fukushima nuclear accident
Shinji Tokonami,Masahiro Hosoda,Suminori Akiba,Atsuyuki Sorimachi,Ikuo Kashiwakura,Ikuo Kashiwakura,Mikhail Balonov +6 more
TL;DR: Detailed measurements of the exposure to I-131 revealing I- 131 activity in the thyroid of 46 out of the 62 residents and evacuees measured are reported for the first time.
Journal ArticleDOI
The time variation of dose rate artificially increased by the Fukushima nuclear crisis
Masahiro Hosoda,Shinji Tokonami,Atsuyuki Sorimachi,Satoru Monzen,Minoru Osanai,Masatoshi Yamada,Ikuo Kashiwakura,Suminori Akiba +7 more
TL;DR: A car-borne survey for dose rate in air was carried out in March and April 2011 along an expressway passing northwest of the Fukushima Dai-ichi Nuclear Power Station which released radionuclides starting after the Great East Japan Earthquake, implying that there were some additional releases from Fukushima NPS.
Journal ArticleDOI
Assessment of the natural radioactivity using two techniques for the measurement of radionuclide concentration in building materials used in Japan
Nabil M. Hassan,Nabil M. Hassan,Tetsuo Ishikawa,Masahiro Hosoda,Atsuyuki Sorimachi,Shinji Tokonami,Masahiro Fukushi,Sarata Kumar Sahoo +7 more
TL;DR: In this article, the specific activities of 238U, 232Th, and 40K in selected building materials used in Japan were measured using a high-purity germanium detector.
Journal ArticleDOI
Effect of Soil Moisture Content on Radon and Thoron Exhalation
TL;DR: In this paper, the effect of soil moisture in the emanation process of radon and thoron gases was considered and a sporadic increase in radon exhalation rates was caused by the increase in the moisture content up to 8%.
Journal ArticleDOI
Radon Migration Process and Its Influence Factors; Review
Nabil M. Hassan,Nabil M. Hassan,Masahiro Hosoda,Tetsuo Ishikawa,Atsuyuki Sorimachi,Sarata Kumar Sahoo,Shinji Tokonami,Masahiro Fukushi +7 more
TL;DR: In this paper, the authors reviewed the emanation coefficient, diffusion coefficient, and exhalation rate, and the factors that control the rate at which radon can enter atmosphere, which is the fraction of radon generated within the grains of materials and escaped to the pore space.
