Exclusion area to be made off-limits

KAWAMATA, Japan - A man checks radiation levels of a bicycle in Kawamata, Fukushima Prefecture, on April 10, 2011, after it was transported from the area within a 30-kilometer radius of the Fukushima Daiichi nuclear power plant. The government will make the area within a 20-km radius of the crisis-hit plant covered by its evacuation directive into an off-limits zone to enhance its control of the area, senior officials said the same day.
