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 energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [2] There is a catastrophic risk potential if containment fails, [3] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...
To combat accidents associated with aging nuclear power plants, it may be advantageous to build new nuclear power reactors and retire the old nuclear plants. In the United States alone, more than 50 start-up companies are working to create innovative designs for nuclear power plants [ 153 ] while ensuring the plants are more affordable and cost ...
Production of parts for nuclear weapons began in 1953. At the time, the precise nature of the work at Rocky Flats was a closely guarded secret. The plant produced fission cores for nuclear weapons, used to "ignite" fusion and fissionable fuel. [12] Fission cores resemble miniaturized versions of the Fat Man nuclear bomb detonated above Nagasaki ...
The focus of the first half of the chapter is designed to provide basic information about atoms and radiation to aid in later chapters. [1] The first half covers the basics on atoms such as: an atom consists of Neutrons, Protons, and Electrons; the atomic number of an atom determines the amount of protons in one atom; and that protons are roughly 2000 times heavier than electrons (see atom).
The Westinghouse nuclear fuel factory southeast of Columbia has had plenty of troubles. But it’s a major player in the nuclear energy industry. Despite water pollution and nuclear spills, SC ...
The building would be an open structure of solid granite or concrete, measuring 40 by 32 by 10 feet (12.2 m × 9.8 m × 3.0 m), and contain Level IV messages. The plans included a suggestion that the building be designed so as to create a "dissonant and mournful" whistling sound when wind blew through it, acting as a Level I message. [1]
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.
