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 ...
Radioactive contamination may also be ingested as the result of eating contaminated plants and animals or drinking contaminated water or milk from exposed animals. Following a major contamination incident, all potential pathways of internal exposure should be considered.
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]
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 ...
(k) water treatment associated with provision of drinking water; or (l) The remediation of contamination from any type 1 NORM industrial activity or any of the activities listed above. An activity which involves the processing of radionuclides of natural terrestrial or cosmic origin for their radioactive, fissile or fertile properties is not a ...
The additional radioactivity in the biosphere caused by human activity due to the releases of man-made radioactivity and of Naturally Occurring Radioactive Materials (NORM) can be divided into several classes. Normal licensed releases which occur during the regular operation of a plant or process handling man-made radioactive materials.
TEPCO's solution resulted in redirection of the groundwater flows, which could have spread the radioactive contamination further. TEPCO also had plans for pumping groundwater. [further explanation needed] At that time the turbine buildings of units 2 and 3 contained 5000 and 6000 cubic meters of radioactive water respectively. With wells in ...
In the 53 municipalities subjected to less than 2 μSv/h, the detection rate ratio was considerably higher: 1.555 (1.096, 2.206). Therefore, it became evident that the radiation contamination due to the Fukushima nuclear power plant accidents is positively associated with the thyroid cancer detection rate in children and adolescents.
