This document summarizes radiological data collected after the Fukushima nuclear accident in Japan on March 25, 2011. Gamma radiation levels exceeded background levels of 0.1 microSievert/hour in some areas. Additional deposition of radioactive iodine-131 and cesium-137 was detected in 7 prefectures, with levels found in food and water samples. The Japanese authority implemented restrictions on distribution of milk, vegetables and drinking water from contaminated areas. Three workers at the plant were exposed to radiation levels under permissible emergency exposure limits. International monitoring teams were assessing radiation levels and food safety.

5. Radioactivity in food and milkRadionuclides abovelevels recommended by the Japanese authorities:I-131 in 5 raw milk samples (Fukushima Prefecture)I-131 in 1 vegetable sample in Ibaraki Prefecture. Cs-137 in vegetable sample in Ibaraki Prefecture

6. Drinking waterAnalysis from 47 prefectures Levels belowthe levels (both adult and children) recommended by the Japanese authorities.

7. Japanese authority measures for food, milk and drinking waterRestrictions on the distribution of:milkin 2prefectures (Fukushima, Ibaraki) certain vegetables in 4 prefectures (Fukushima, Ibaraki, Tochigi, Gunma). Requested sampling of agricultural products in 6 neighbouring prefectures (Miyagi, Yamagata, Saitama, Chiba, Niigata and Nagano).
