Tokyo (CNN) — Radiation readings near tanks holding toxic water at Japan’s crippled nuclear power plant have jumped to a new high, the plant operator said Wednesday.
Tokyo Electric Power Company, which has been struggling to deal with a series of leaks at the Fukushima Daiichi nuclear plant, said it detected a radiation level of 2,200 millisieverts near the tanks on Tuesday. That’s up from a previous high of 1,800 millisieverts on Saturday.
Those levels, detected around the same tank, are strong enough to kill an unprotected person within hours. But TEPCO said the type of radiation is easy to shield against.
The water leaking from the tank has lethal levels of radioactivity. This is one tank out of about a thousand that are storing the radioactive waste water. These tanks are bolted together with the life expectancy of about 5 years. With time one would expect more leaks as the tanks integrity deteriorates.
The operator of the wrecked Fukushima nuclear plant said on Friday it found elevated readings of tritium in groundwater near tanks that are holding hundreds of tonnes of contaminated water at the site. Tokyo Electric Power Co (Tepco) said tritium levels in water taken from a well close to a number of storage tanks holding irradiated water rose to 97,000 becquerels per litre on Wednesday from 64,000 becquerels/litre measured at the same location a day earlier.
As a reminder, the first report above reports total irradiation; the second report identifies how much can be attributed to water and does not identify any of the many other nucleotides such as carbon, cesium, strontium, etc.
