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).
Nuclear power plants in normal operation emit less radioactivity than coal power plants. [69] [70] Unlike coal-fired or oil-fired power generation, nuclear power generation does not directly produce any sulfur dioxide, nitrogen oxides, or mercury (pollution from fossil fuels is blamed for 24,000 early deaths each year in the U.S. alone [71 ...
The radiation effects from the Fukushima Daiichi nuclear disaster are the observed and predicted effects as a result of the release of radioactive isotopes from the Fukushima Daiichii Nuclear Power Plant following the 2011 TÅhoku 9.0 magnitude earthquake and tsunami (Great East Japan Earthquake and the resultant tsunami).

Fewer clean nuclear power plants led to increased air pollution from fossil fuel–fired plants. That extra air pollution killed far more people than the meltdown, by several orders of magnitude.
A 1000-megawatt nuclear power plant produces about 27 tonnes of spent nuclear fuel (unreprocessed) every year. [44] For comparison, the amount of ash produced by coal power plants in the United States is estimated at 130,000,000 t per year [45] and fly ash is estimated to release 100 times more radiation than an equivalent nuclear power plant. [46]
Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences and damage to the environment. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and ...
After discovering the contamination, 10 workers were evacuated from WIPP’s Waste Handling Building and tested for radioactive contamination.
