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 ...
The center is a 501(c)(3) non-profit corporation an, as of 2014, has one full-time employee. On October 15, 1983, about 10,000 demonstrators turned out for protest at the Rocky Flats Nuclear Weapons Plant (well short of the 21,000 hoped for by protest organizers). No arrests were made.
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).
Nuclear Waste Policy Act of 1982 as amended (PDF/details) in the GPO Statute Compilations collection; Summary of Nuclear Waste Policy Act can be found on the EPA site: EPA Laws & Regulations "Low-Level Radioactive Waste Policy Act – P.L. 96-573" (PDF). U.S. Senate Bill S. 2189 ~ 94 Stat. 3347. U.S. Government Printing Office.
The prussian blue reduces the biological half-life (not to be confused with the nuclear half-life) of the caesium). The physical or nuclear half-life of 137 Cs is about 30 years, which is a constant and can not be changed; however, the biological half-life will change according to the nature and habits of the organism for which it is expressed.
Downwinders were individuals and communities, in the United States, in the intermountain West between the Cascade and Rocky Mountain ranges primarily in Arizona, Nevada, New Mexico, and Utah but also in Oregon, Washington, and Idaho who were exposed to radioactive contamination or nuclear fallout from atmospheric or underground nuclear weapons testing, and nuclear accidents.
Bioremediation of radioactive waste or bioremediation of radionuclides is an application of bioremediation based on the use of biological agents bacteria, plants and fungi (natural or genetically modified) to catalyze chemical reactions that allow the decontamination of sites affected by radionuclides.
