On 5 April 2011, the operator of the nuclear plant, Tokyo Electric Power Company (TEPCO), discharged 11,500 tons of untreated water into the Pacific Ocean in order to free up storage space for water that is even more radioactive. The untreated water was the least radioactively contaminated among the stored water, but still 100 times the legal ...
[3] [4] The release of radioactive isotopes from reactor containment vessels was a result of venting in order to reduce gaseous pressure, and the discharge of coolant water into the sea. [5] This resulted in Japanese authorities implementing a 30-km exclusion zone around the power plant and the continued displacement of approximately 156,000 ...
In order to prevent the outflow of the highly radioactive water at the turbine building of Unit 2, the water was transferred to the Centralized Radiation Waste Treatment Facility since 19 April. TEPCO planned to install facilities for processing the stored water and reusing treated water to inject it into the reactors. [60] On 11 May
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 ...
The filtering process will remove strontium-90 and iodine-129, and the concentration of carbon-14 in the contaminated water is far lower than its regulatory standard for discharge, according to ...
Workers stand on grating about the Hanford site K West Reactor basin to sort debris at the bottom of the 16-foot-deep pool. The work was needed to start pumping contaminated water from the basin.
When radioactive contamination is being measured or mapped in situ, any location that appears to be a point source of radiation is likely to be heavily contaminated. A highly contaminated location is colloquially referred to as a "hot spot." On a map of a contaminated place, hot spots may be labeled with their "on contact" dose rate in mSv/h.
