Tons of radioactive water has been leaking from a tank at the Fukushima Daiichi Nuclear Disaster site in Japan, and the leak had apparently been going on for a month before engineers found it.

At least 300 tons of liquid was missing from the storage tank located on the plant grounds.  The Tokyo Electric Power Company (TEPCO) claimed that none of the water, which had been used to cool the three reactors which melted-through two years ago, had flowed directly into the Pacific Ocean.  It could be that the water leaked directly into the soil, but being as the tank is 500 meters from the Pacific Ocean, it’s impossible to stop any leaks from draining into the sea.  TEPCO also admits the leaked water contains 80 million Becquerels of radiation per liter, from deadly substances such as Strontium.

But what’s even more alarming, is that TEPCO doesn’t know which part of the tank is leaking; the operator only knows that the water is missing.

Meanwhile, another two workers were dusted with radioactive particles, the second such incident in a week involving staff outside the site’s main operations center.  Last week, 10 workers were found to have been contaminated with radiation coming from the cooling mister outside the plant, originally installed to deal with Japan’s blistering hot summer.
