According to Tepco, high level of Strontium-90 is still measured in sub-drain of reactor2 and 3. The data of reactor1 is not published for some reason. The sampling date was 11/12/2012. Tepco took 6 months to publish the data. They measured 56,000 Bq/m3 of Strontium-90 from sub-drain of reactor2. They also measured 67 Bq/m3 of [...]

Posted by Mochizuki on May 22nd, 2013
Having the contaminated water keep increasing, Tepco is running out of the storage. Tepco made 7 reservoirs, but so far, Tepco has admitted 3 of them are leaking. In order to investigate how far the leaking contaminated water is penetrating underground, Tepco is analyzing ground water of observation holes and bypass wells. According to Tepco, [...]
