Other sources of groundwater contamination included: radioactive waste dumps on the territory of “exclusion zone”; cooling water reservoirs connected with aquifer; initial radioactive fallout which took place in first hours after the accident; and forest fires that led to accelerated spread of contaminated particles on soils of the ...
Highly radioactive water leaked from a treatment machine at the tsunami-hit Fukushima Daiichi nuclear power plant, but no one was injured and radiation monitoring shows no impact to the outside ...
Japan is deploying a specialized system called advanced liquid processing system, which according to the IAEA’s report, is a “pumping and filtration system” that uses a series of chemical ...
Tritium, a radioactive substance, was not found in the most recent sample collected from fish near the Fukushima Daiichi nuclear plant, where treated radioactive water was released into the sea.
In addition to the large releases of contaminated water (520 tons and 4.7 PBq [74] [91]) believed to have leaked from unit 2 from mid-March until early April, another release of radioactive water is believed to have contaminated the sea from unit 3, because on 16 May TEPCO announced seawater measurements of 200 Bq per cubic centimeter of ...
The U.N. nuclear agency gave its endorsement on Tuesday to Japan’s planned release of treated radioactive wastewater into the sea from the damaged Fukushima nuclear plant, saying it meets ...
