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). [3]
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 ...
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).
This is a list of books about nuclear issues. They are non-fiction books which relate to uranium mining, nuclear weapons and/or nuclear power. The Algebra of Infinite Justice (2001) American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer (2005) The Angry Genie: One Man's Walk Through the Nuclear Age (1999)
Long-term nuclear waste warning messages are communication attempts intended to deter human intrusion at nuclear waste repositories in the far future, within or above the order of magnitude of 10,000 years. Nuclear semiotics is an interdisciplinary field of research, first established by the American Human Interference Task Force in 1981.
