Fukushima radioactivity levels spike

Radioactivity levels at Japan's Fukushima nuclear power plant on Thursday were 6,500 times higher than the previous day's readings, Russia's RT reports.

A tank at the crippled power plant leaked 300 tonnes of toxic water in August. Samples taken from a nearby well on Thursday indicated that the water contained the highest levels of eta-ray emitting substances since March 2011 when a tsunami triggered a nuclear accident.

Tokyo Electric Power Company (TEPCO) says it will "remove any contaminated soil around the storage tank in an effort to monitor radioactivity levels of the water around the well," RT reports.

"Other wells are not showing such a high level. We need to take additional measures for the areas around this well," a TEPCO spokesman told reporters on Friday, as reported by Phys Org.

The company suspects that heavy rainfall caused by this week's typhoon could have washed contaminated materials into the well.

TEPCO has faced increasing criticism lately over its handling of the 2011 disaster, especially since admitting that some contaminated water may have enetred the sea.
