Gamma Dose Rates in microSievert per hour 15-24 March<br />Background: 0.1 microSv/hour<br />
Deposition of I-131 and Cs-13723 to 24 March <br />Monitored by Japanese authority<br />47 Prefectures<br />Additional deposition detected in 7 prefectures<br />I-131: 42 to 16000 Bq/m2<br />Cs-137: 42 to 210 Bq/m2<br />I-131 Rate of deposition is decreasing (21 to 24 March)<br />[Tokyo: 320003600013000]<br />
IAEA radiation monitoring team 25/03/11<br />Radius 34 to 62 km for NPP measurement of :<br />Contamination: 0.07 to 0.96 MBq/ m2<br />Dose rate: 0.73 to 8.8 microSv/ hour (background: 0.1 microSv/ hour)<br />Lower than yesterday<br />
Radioactivity in food and milk<br />Radionuclides abovelevels recommended by the Japanese authorities:<br />I-131 in 5 raw milk samples (Fukushima Prefecture)<br />I-131 in 1 vegetable sample in Ibaraki Prefecture. <br />Cs-137 in vegetable sample in Ibaraki Prefecture<br />
Drinking water<br />Analysis from 47 prefectures <br />Levels belowthe levels (both adult and children) recommended by the Japanese authorities. <br />
Japanese authority measures for food, milk and drinking water<br />Restrictions on the distribution of:<br />milkin 2prefectures (Fukushima, Ibaraki) <br />certain vegetables in 4 prefectures (Fukushima, Ibaraki, Tochigi, Gunma). <br />Requested sampling of agricultural products in 6 neighbouring prefectures (Miyagi, Yamagata, Saitama, Chiba, Niigata and Nagano).<br />
3 workers affected by radiation<br />3 workers exposed: 173-180 milliSv<br />2 of these 3 workers: Feet exposed to contaminated water<br />Dose permissible for emergency workers in life saving operation: 250 milliSv<br />
