FUKUSHIMA — A decade from now, airborne radiation levels in some parts of Fukushima Prefecture are still expected to be dangerous at above 50 millisieverts a year, a government report says.
The report, which contains projections through March 2032, was presented by trade minister Yukio Edano Sunday to leaders of Futaba, one of the towns that host the crippled Fukushima No. 1 power plant.
The report includes radiation forecasts for 2012 to 2014, and for 2017, 2022 and 2032, based on the results of monitoring in November last year. It was compiled to help municipalities draw up recovery and repopulation programs for the nuclear disaster.
The forecasts do not take into account experimental decontamination efforts.
Earlier this month, the government designated areas where annual radiation dosage exceeds 50 millisieverts as those likely to remain off-limits to evacuees in the near term.
The report said that annual radiation levels in March 2022 will probably exceed 50 millisieverts in some of the areas, including Futaba and Okuma, the other town that hosts the radiation-leaking plant.
