Radiation levels around the boundary of the crippled Fukushima No. 1 nuclear plant have risen to eight times the government standard of 1 millisievert per year, Tokyo Electric Power Co. said.
 The Nuclear Regulation Authority is scheduled to hold a meeting Jan. 10 to discuss countermeasures for a southern area on the plant site that has long been a source of problems.
 A level of 8 millisieverts per year was estimated as of December near an area with many storage tanks containing highly radioactive water, company officials said.
 After water leaks from underground tanks on the plant’s premises were found last April, the utility transferred radioactive water to the aboveground storage tanks near the southern boundary, TEPCO officials said. The readings there were estimated at 7.8 millisieverts per year as of May.
TEPCO said the main factor behind the increase in radiation levels was X-rays from the storage tanks.
Beta rays released from radioactive strontium and other substances in the water reacted with iron and other elements in the storage tank containers to generate the X-rays, the officials said.
