Two IAEA teams are currently monitoring radiation levels and radioactivity in the environment in Japan.
On 29 March, one team made gamma dose-rate measurements in the Tokyo region at 8 locations.
Gamma-dose rates measured ranged from 0.02 to 0.19 microsievert per hour, which is within or slightly
above the background.
The second team made additional measurements at distances of 32 to 62 km, at directions North to
Northwest from the Fukushima nuclear power plant. At these locations, the dose rates ranged from
0.5 to 6.8 microsievert per hour. At the same locations, results of beta-gamma contamination measurements
ranged from 0.05 to 0.45 Megabecquerel per square metre.
Based on measurements of I-131 and Cs-137 in soil, sampled from 18 to 26 March in 9 municipalities at
distances of 25 to 58 km from the Fukushima Nuclear Power Plant, the total deposition of iodine-131 and
cesium-137 has been calculated. The results indicate a pronounced spatial variability of the total deposition
of iodine-131 and cesium-137. The average total deposition determined at these locations for iodine-131
range from 0.2 to 25 Megabecquerel per square metre and for cesium-137 from 0.02-3.7 Megabecquerel
per square metre. The highest values were found in a relatively small area in the Northwest from the
Fukushima Nuclear Power Plant. First assessment indicates that one of the IAEA operational criteria for
evacuation is exceeded in Iitate village. We advised the counterpart to carefully assess the situation.
hThey indicated that they are already assessing.
