福島第一原子力発電所事故後の環境中における放射性セシウム濃度に関する研究［第4部］

抄録

The Tohoku-Pacific Ocean Earthquake that occurred on March 11, 2011 and the resulting tsunami caused the loss of many people and extensive damage in a wide area. Among the anthropogenic radionuclides dispersed from the Fukushima Daiichi Nuclear Power Plant, ¹³⁴Cs and ¹³⁷Cs have very long half-lives of approximately 2 years and 30 years, respectively, and there are concerns about their uptake into soil and living things. This paper describes a study conducted by the authors’ group on radiocesium activity concentrations in the environment.
