The document summarizes radiation monitoring and consequences from the Fukushima Nuclear Accident in Japan on April 12, 2011. It provides data on gamma dose rates across 7 prefectures from March 24 to April 12 and across 47 prefectures on April 11. It also gives daily deposition levels of radioactive isotopes I-131 and Cs-137 from April 1 to 11. Monitoring of drinking water, foodstuffs, and other samples found radiation levels were far below restriction levels across prefectures, with one village issuing precautions for infants based on detected I-131 levels.
