Accumulated radiation latest worry for towns.
Its math, a little bit of radiation over a loooong time equals a Lot of Radiation.
The accumulated radiation level in Namie, 30 km from the crippled Fukushima No. 1 nuclear power plant, stood at 17,010 microsieverts, according to a tally released by the science ministry Saturday.
The accumulated levels during the period starting March 23 through Friday stood at 9,850 microsieverts in Iitate and 495 microsieverts in Minamisoma, it said. The readings compare with the 1,000 microsieverts that residents of the country can expect to be exposed to during one year.
The amount of radioactive cesium stood at between 12.7 and 71.0 becquerels per liter of surface seawater near the plant Monday and Wednesday, and 10.1 becquerels at deeper levels Monday, the science ministry added.
