The operator of Japan™s Fukushima nuclear power plant says that high levels of radiation have been found in groundwater from an observation well near the site of a leaky storage tank.
Tokyo Electric Power Company (TEPCO) said on Monday that the water from the monitoring well contained 3,200 becquerels per liter of beta-ray emitting materials, including strontium, AFP reported.
TEPCO said that the finding means that it “now seems more likely” that radioactive water from leaking tanks had mixed with groundwater in the area.
Last week, Japan’s Nuclear Regulation Authority (NRA) and the plant operator said that radiation levels around tanks storing contaminated water at the crippled nuclear plant had risen by a fifth to a new high.
Readings just above the ground near one set of tanks at the plant showed radiation as high as 2,200 millisieverts (mSv), NRA and TEPCO reported.
On March 11, 2011, Japan was hit by a 9.0-magnitude earthquake followed by a devastating tsunami that ravaged through the country’s northeastern coast.
The earthquake and tsunami knocked out cooling systems to reactors at the Fukushima plant, three of which melted down.
Water is now being pumped in to cool the reactors, but storing the resultant large quantities of radioactive water has proved a challenge for TEPCO.
The Fukushima plant has leaked radiation into air, soil and the Pacific Ocean ever since it was hit by the massive earthquake and tsunami.
