Nuclear radiation at the boundaries of the stricken Fukushima power plant has now reached 8 times government safety guidelines, TEPCO has said. The firm has been struggling to contain radioactive leaks at Fukushima since the onset over the crisis in 2011.

The levels of nuclear radiation around Fukushima’s No. 1 plant have risen to 8 millisieverts per year, surpassing the government standard of 1 milliseviert per year, reports news site Asahi Shimbun citing Tokyo Electric Power Company (TEPCO).

The Nuclear Regulation Authority held a meeting on Friday aimed at curbing the rising levels of radiation to the south of the plant, which has long been a problem area.

TEPCO told press that the predominant reason behind the sharp increase in radiation at the plant was X-rays coming from storage tanks holding radioactive water that has been leaking from the Fukushima facility.

The water in the tanks contains traces of radioactive strontium along with other substances that react with the materials the tank is composed of, producing X-rays, said officials.

Strontium-90 is a radioactive isotope of strontium produced by nuclear fission with a half-life of 28.8 years.

Radioactive water leaking from the nuclear site at Fukushima has been a pressing concern to the international community, as well as the Japanese population since the outbreak of the crisis in March 2011.
