TOKYO, October 18. (Itar-Tass) – Tokyo Electric Power (TEPCO) reported rapid increase in the number of radioactive particles in Fukushima-1 water samples – the increase was recorded twice in one day.
The company reported 790,000 becquerels of tritium, a radioactive isotope of Hydrogen, per liter; normal values do not exceed 150. Friday morning levels were measured at 400,000 becquerels per liter. TEPCO noted that in the last 24 hours the amount of radioactive substances in water has increased by the order of 12,000. This is the most severe case of radioactivity escalation in the vicinity of the nuclear facility so far.
Representatives of the company said that the latest sample was taken in a well located around 10 meters from the damaged tank, through which around 300 tons of radioactive water leaked this July and August.
This is the most serious incident since the 2011 Fukushima disaster.
Earlier this week increased radiation levels were recorded in the water of the plant’s drainage tunnel leading to the ocean. 1400 becquerels of strontium and other beta-radiating substances per liter were recorded. This is 30 times more than the allowed amount for dumping water into the ocean.
