Radiation, Health and Food Safety Information Post-Fukushima
More than two years after the accident, the Fukushima Daiichi nuclear power plant is stable, but still severely damaged. The Tokyo Electric Power Company (TEPCO) is working with Japanese government agencies to address leaks of contaminated water on the site. TEPCO and Japanese government agencies routinely monitor levels of radiation in the seawater near the Fukushima Daiichi nuclear power plant to identify contamination levels. TEPCO provides regular technical updates in English of its efforts and radiation monitoring.
Japanese authorities have not identified any radiation levels, outside of restricted access areas, that increase radiation exposure risks for residents of Japan. Japanese authorities also conduct regular inspections of food and tap water and have not identified any increased radiation levels. For more information on these efforts and to view the latest results, please see the links below.
About radiation exposure or contamination
The U.S. Centers for Disease Control and Prevention and the Environmental Protection Agency (EPA) provide helpful information about radiation and its health effects.
- EPA information on Radiation Doses in Perspective.
- Additional visual presentations of radiation dose from Japan's National Institute of Radiological Sciences.
As in the United States, the Japanese government has set standards for radioactive material in food and beverages to protect public health. Japan's Cabinet Office posted an English summary of Food Safety in Japan following the 2011 nuclear accident. (The pdf can also be found here.)
Radioactivity measurements in food, water, and the environment are collected and updated regularly by Japan's Nuclear Regulation Authority. The Nuclear Regulation Authority divides responsibilities for radiation monitoring with several other agencies, in accordance with its Comprehensive Radiation Monitoring Plan.
Japan's Ministry of Health, Labor and Welfare (MHLW) is responsible for food safety in agricultural, forestry, livestock, and fishery products. MHLW regularly updates its English language website with information on the safety of water and specific foods in Japan.

- The U.S. Department of Defense Operation Tomodachi Registry provides radiation exposure estimates for DOD-affiliated individuals who were in or near Japan immediately after the March 2011 accident. The site also has location-based radiation dose estimates.
- Tokyo Metropolitan Government's website provides hourly radiation levels monitored at eight locations in Tokyo, including Shinjuku, Ota, and Adachi wards, as well as the results of fallout, tap water and food sampling testing conducted by the metro government. The website also provides all the past radiation readings Tokyo has monitored since 2011. In Japanese and English.
