Radioactivity level spikes 6,500 times at Fukushima well
October 18, 2013
Radioactivity levels in a well near a storage tank at the Fukushima nuclear power plant in Japan have risen immensely on Thursday, the plant’s operator has reported.
Officials of the Tokyo Electric Power Company (TEPCO) said on Friday they detected 400,000 becquerels per liter of beta ray-emitting radioactive substances – including strontium – at the site, a level 6,500 times higher than readings taken on Wednesday, NHK World reported.
The storage tank leaked over 300 tons of contaminated water in August, some of which is believed to have found its way into the sea through a ditch.
The well in question is about 10 meters from the tank and was dug to gauge leakage.
TEPCO said the findings show that radioactive substances like strontium have reached the groundwater. High levels of tritium, which transfers much easier in water than strontium, had already been detected.
Officials at TEPCO said they will remove any contaminated soil around the storage tank in an effort to monitor radioactivity levels of the water around the well.
The news comes after it has been reported a powerful typhoon which swept through Japan led to highly radioactive water near the crippled nuclear power plant being released into a nearby drainage ditch, increasing the risk of it flowing into the sea.
On Wednesday TEPCO said it had detected high levels of radiation in a ditch leading to the Pacific Ocean, and that it suspected heavy rains had lifted contaminated soil.
New leak of radioactive water at Fukushima nuclear plant may have flowed into Pacific Ocean: TEPCO
(ABC/Reuters) The operator of the crippled Fukushima nuclear plant says it has found a new leak of radioactive water that might have flowed into the Pacific Ocean.
The leak from the 450-tonne storage tank is the second of its kind in as many months, and involved water with high concentrations of radioactive strontium and caesium.
Fukashima operator Tokyo Electric Power (TEPCO) says it does not know how much water leaked, adding that it could have flowed from an adjoining drainage ditch into the sea.
TEPCO has apologised for causing anxiety.
Last month, 300 tonnes of highly contaminated water leaked from a tank and some is believed to have flowed into the Pacific.
