Radiation some 1.4 times the legal annual dose limit has been detected in a town near the damaged nuclear power station in Fukushima Prefecture, northeastern Japan, the science ministry said Saturday.
Against the exposure limit of 1,000 microsieverts a year for an average Japanese, the radiation amount increased to total 1,437 microsieverts in Namie, 30 kilometers northwest of the Fukushima No. 1 nuclear plant, in only 24 hours from 12:15 p.m. Wednesday, the ministry said.
The radiation level was relatively high, but not high enough to affect human health, the Nuclear Safety Commission said.
At around 2:30 p.m. Friday, Namie’s radiation level stood 2,828 microsieverts, with the per-hour radiation dose coming to 56 microsieverts, the ministry said.
Meanwhile, a total of 52 microsieverts of radiation was measured near the Fukushima prefectural government building, 60 kilometers northwest of the nuclear plant, during a 27-hour monitoring period, it said.
