Watch a view of Japan's Fukushima nuclear power plant on Friday, 25 August, as it begins to discharge treated radioactive water into the Pacific Ocean. A massive earthquake and tsunami caused ...
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 ...
Since the accumulated radioactive water was a risk, TEPCO tried to transfer it. Assembly of hose fittings for Fukushima complex, Yokota AB. As the accumulated water in the basement of the turbine building of Units 2 and 3 was radioactive, TEPCO needed to remove it. They had initially planned to pump the water to the condenser (see diagram).
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 ...
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 ...
[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 ...
The discharge plan kicked off in August in a key step towards decommissioning the plant, which suffered meltdowns after being hit by a tsunami in 2011 in the world's worst such nuclear disaster ...
In water, broad electron beams, as is the case in homogeneous surface contamination of skin, have d 80 about E/3 cm and R p about E/2 cm, where E is the beta particle energy in MeV. [ 24 ] The penetration depth of lower-energy beta in water (and soft tissues) is about 2 mm/MeV.
