" Radiation measurements have exceeded levels at which people are advised to stay indoors in a town outside the 30-kilometer radius of the damaged Fukushima Daiichi nuclear plant.
The science ministry continues to monitor radiation levels in areas where residents have not been advised by the government to evacuate or stay indoors.
The monitoring detected 10.3 millisieverts of radiation at one location in Namie Town, some 30 kilometers northwest of the plant.
The amount is calculated on the assumption that a person has remained outdoors for 11 consecutive days through Sunday.
The finding is higher than the 10 millisieverts the government views as the criteria for remaining indoors.
The Nuclear and Industrial Safety Agency says that as the radiation level was only detected in a limited area, it has no intention of expanding the indoor advisory zone at present.
A nuclear expert has pointed out that the government should explain the details of the finding to the residents."
