FUKUSHIMA — The government on April 22 released six hot spot charts to show projected annual dose rates of radioactive materials spewing from the crippled Fukushima No. 1 Nuclear Power Plant from the end of March this year through 2032.
The charts, based on airborne monitoring of radioactive contamination in November last year, compare annual dose rates in March this year with projections for 2013, 2014, 2017, 2022 and 2032.
Tatsuo Hirano, state minister in charge of post-March 11 reconstruction and disaster prevention, says, “They are prognostic charts based on theoretical values but decontamination factors were not taken into account.” It is the first time that the government has made public such forecasts.
The government produced the charts which focus on areas with high levels of radiation contamination extending in the northwestern direction in Fukushima Prefecture. Government officials say the charts will help local governments affected by the nuclear disaster to draw up a plan to assist evacuees in returning home.
The projections reveal that borders along the towns of Okuma and Futaba, where the Fukushima plant is located, will remain as zones with an annual radiation dose of more than 50 millisieverts, which are basically difficult for residents to return to live even after 20 years. The town of Namie and the village of Katsurao will continue to have restricted districts due to annual radiation doses of over 20 millisieverts and below 50 millisieverts.
The central government presented the charts during a meeting in Fukushima with leaders of the prefecture’s eight towns and villages around the nuclear plant.
