Japan: protective measures continue

June -- Japan's Nuclear and Industrial Safety Agency has announced that the amount of radiation emitted during the first week of the Fukushima nuclear plant incident is double the initial estimate. At this time, based on the updated information, there are no additional measures recommended beyond earlier actions taken, but the situation is under assessment. Earlier public health actions implemented immediately after the incident (i.e. evacuation, sheltering), as well as the additional protective actions taken later based on the results of the environmental monitoring (relocation of populations in other villages), have been the correct protective measures to protect those populations from radiation exposure. These measures reflect basic principles on protecting populations against radiation.
