Japan published a map of radioactive accumulation

Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) on June 21 published a map of the distribution of radioactive concentrations accumulated in the past three months after the earthquake and tsunami. history March 11.

According to this map, the amount of radiation measured outside the 20km radius around Fukushima 1 nuclear power plant is quite high.

Radiation accumulation map provides another view of external radiation risk
20km dangerous area around the factory.

This raises concerns about the safety of the area outside the 20km radius, which is assessed as less dangerous. Specifically, in Namie Town, only 22km northwest of the factory, the cumulative radiation concentration reached 82 milisievert.

MEXT said the department has gathered measurement data at 2,734 locations in Fukushima Prefecture to create this map, and will update the map data twice a month.

According to published data, MEXT has pointed out 160 locations outside the restricted area, including a total of 23 locations with cumulative radiation exceeding 20 milisievert.

All 23 locations are in the migration area as planned due to 20 millisievert of accumulated radiation within a year. However, the level of real concern is greater than the previous calculation when the measured value here exceeded 20 milisievert after only three months.
