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).
One of four example estimates of the plutonium (Pu-239) plume from the 1957 fire at the Rocky Flats nuclear weapons plant. The Rocky Flats Plant, a former United States nuclear weapons production facility located about 15 miles (24 km) northwest of Denver, caused radioactive (primarily plutonium, americium, and uranium) contamination within and outside its boundaries.

Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.
Erosion of the 150-millimetre-thick (5.9 in) carbon steel reactor head at Davis-Besse Nuclear Power Plant, in Oak Harbor, Ohio, USA, in 2002, caused by a persistent leak of borated water The Hanford Site, in Benton County, Washington, USA, represents two-thirds of America's high-level radioactive waste by volume.
The Soviet Union 874 TBq, US 554 TBq, Japan 606.2 Tonnes, New Zealand 1+ TBq. 751,000 m 3 was dumped by Japan and the Soviet Union. The United States reported neither tonnage nor volume of 56,261 containers. Dumping of contaminated water at the 2011 Fukushima nuclear accident (estimate 4,700–27,000 TBq) is not included.
Because of their long half-lives, TRUW is disposed of more cautiously than either low- or intermediate-level waste. In the United States, it arises mainly from nuclear weapons production, and consists of clothing, tools, rags, residues, debris, and other items contaminated with small amounts of radioactive elements (mainly plutonium).
It shows what the US, from California to Ohio to New York, looked like from 1971 to 1977. Of the 81,000 images the photographers took, more than 20,000 photos were archived, and at least 15,000 ...
Releases of man-made radioactive materials which occur during an industrial or research accident. For instance the Chernobyl accident. Releases which occur as a result of military activity. For example, a nuclear weapons test, which have caused a global fallout, peaking in 1963 (the Bomb pulse), and up to 2.4 million deaths by 2020. [5]
