  2. Radioactive contamination - Wikipedia

    en.wikipedia.org/wiki/Radioactive_contamination

    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. High-level radioactive waste management - Wikipedia

    en.wikipedia.org/wiki/High-level_radioactive...

    Radioactive decay follows the half-life rule, which means that the intensity of radiation decreases over time as the rate of decay is inversely proportional to the duration of decay. In other words, the radiation from a long-lived isotope like iodine-129 will be much less intense than that of short-lived isotope like iodine-131. [4]

    The classification of radioactive waste established by the International Atomic Energy Agency (IAEA) distinguishes six levels according to equivalent dose, specific activity, heat released and half-life of the radionuclides: [13] Exempt waste (EW): Waste that meets the criteria for exclusion from regulatory control for radiation protection ...

    Nevada, Washington, and South Carolina threatened to close their sites unless Congress acted to give them greater control. [5] To relieve this problem and at the same time to accelerate action, Congress passed the Low Level Radioactive Waste Policy Amendments Act of 1985 (P.L. 99-240).

  7. Ocean disposal of radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Ocean_disposal_of...

    The first conversations surrounding dumping radioactive waste into the ocean began in 1958 at the United Nations Law of the Sea Conference (UNCLOS). [12] The conference resulted in an agreement that all states should actively try to prevent radioactive waste pollution in the sea and follow any international guidelines regarding the issue. [12]

  8. Radiation protection - Wikipedia

    en.wikipedia.org/wiki/Radiation_protection

    There are three factors that control the amount, or dose, of radiation received from a source. Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator ...

  9. Environmental radioactivity - Wikipedia

    en.wikipedia.org/wiki/Environmental_radioactivity

    The additional radioactivity in the biosphere caused by human activity due to the releases of man-made radioactivity and of Naturally Occurring Radioactive Materials (NORM) can be divided into several classes. Normal licensed releases which occur during the regular operation of a plant or process handling man-made radioactive materials.
