Role of the Wastewater Treatment System in the Behavior of Radioactive Cesium Precipitated in the Urban Area of Tokyo
The risk of radioactive contamination of densely populated urban areas is not due only to the leakage of radioactive materials from nuclear power plants and nuclear fuel reprocessing plants. Nuclear batteries and depleted uranium loaded on satellites and

Preface
When the Chernobyl nuclear disaster struck, a famous Japanese professor specialized in nuclear engineering, who also served as a member of a committee in the Japanese government, asserted that such a stupid accident would not occur in Japanese nuclear power plants. Twenty-five years later, the Fukushima nuclear disaster happened, and ANZENSHINWA in Japan collapsed, which is a Japanese word meaning safety myth. This accident was more significant than the Chernobyl accident in terms of emissions of radioactive material. Did Japanese nuclear engineering experts seriously study the experience of the Chernobyl accident? Many nuclear experts in Japan may have assumed that a severe accident leading to nuclear fuel meltdown would not occur. However, in the Fukushima Daiichi Nuclear Power Plant (FDNPP), where six boiling water reactors were operating, three reactors and four reactor buildings collapsed. Moreover, the Tokyo metropolitan area, which is more than 200 km from the FDNPP site, was exposed to a significant radioactive contamination. This event was a severe incident. This book aims to help readers understand the actual situation of
