The Great East Japan Earthquake that occurred on March 11, 2011, triggered the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant accident (hereafter referred to as FDNPP Accident), releasing a large amount of radioactive material into the environment. As a result, industries that support our food supply, such as agriculture, forestry, fisheries, and livestock farming, were severely affected, making ensuring food safety an urgent issue.
 
Since the FDNPP accident, the Graduate School of Agricultural and Life Sciences at the University of Tokyo has been conducting research across the department to elucidate the behavior of radioactive substances and develop measures to reduce their presence in crops. This book is the fourth book in a series published a decade after the accident. The entire series (four books in total) is freely available as an open-access publication.
 
Regarding the publication of this book, the website provides the following description:
 
This open access book presents the findings from on-site research into radioactive cesium contamination in various agricultural systems affected by the Fukushima Daiichi Nuclear Power Plant accident in March 2011. This fourth volume in the series reports on studies undertaken at contaminated sites such as farmland and forests, focusing on soil, water, mountain, agricultural products, and animals. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. In the series of this book, a real-time radioisotope imaging system has been introduced, a pioneering technique to visualize the movement of cesium in soil and in plants. This is the only book to provide systematic data on the actual change of radioactivity, which is of great value to all researchers who wish to understand the effect of radioactive fallout on agriculture. In addition, it helps the general public better understand radio-contamination issues in the environment. The project is ongoing; the research groups from the Graduate School of Agricultural and Life Sciences of 春雨直播app continue their work in the field further to evaluate the long-term effects of the Fukushima accident.
