Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
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 ...
The radiological activity was the same for all seedlings, but not the duration of exposure (descending from left to right, the fourth as control). Those exposed for longer suffered more damage and higher growth and germination deficiences. [19] Radiation tests in model organisms that determine the effects of high radiation on animals and plants ...
Radioactive waste is a type of hazardous waste that contains radioactive material.It is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare-earth mining, and nuclear weapons reprocessing. [1]
Tests found no evidence of radioactive contamination in 2015. Investigations have also been carried out in the past on sand dunes near Kinloss in Moray. Ra-226 is a radioactive substance found in ...
The Japanese government had initially requested the assistance of the Russian floating water decontamination plant Landysh to process the radioactive water from the damaged reactors, but negotiations with the Russian government were an extremely slow process and it is unclear if the plant was ever sent to Fukushima.
