  2. Radioactive contamination - Wikipedia

    en.wikipedia.org/wiki/Radioactive_contamination

    Radioactive contamination can be due to a variety of causes. It may occur due to the release of radioactive gases, liquids or particles. For example, if a radionuclide used in nuclear medicine is spilled (accidentally or, as in the case of the Goiânia accident, through ignorance), the material could be spread by people as they walk around.

  3. Radionuclide - Wikipedia

    en.wikipedia.org/wiki/Radionuclide

    The radioactive decay can produce a stable nuclide or will sometimes produce a new unstable radionuclide which may undergo further decay. Radioactive decay is a random process at the level of single atoms: it is impossible to predict when one particular atom will decay.

  4. Nuclear and radiation accidents and incidents - Wikipedia

    No immediate fatalities, though up to 200+ additional cancer deaths might have ensued from the radioactive contamination of the surrounding area; 270,000 people were exposed to dangerous radiation levels. Over thirty small communities were removed from Soviet maps between 1958 and 1991. [67] (INES level 6) [32] October 1957: Windscale fire, UK ...

  5. Long-term nuclear waste warning messages - Wikipedia

    en.wikipedia.org/wiki/Long-term_nuclear_waste...

    Proposed pictogram warning of the dangers of buried nuclear waste for the Waste Isolation Pilot Plant. 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.

  6. Effects of nuclear explosions on human health - Wikipedia

    en.wikipedia.org/wiki/Effects_of_nuclear...

    Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.

  7. Radioactive decay - Wikipedia

    en.wikipedia.org/wiki/Radioactive_decay

    Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.

    I first discovered Somavedic by its beauty and thought it was an art piece for your home. When I dug deeper I found out the device is a chic-looking, glowing orb of glass that claims to neutralize ...

    en.wikipedia.org/wiki/List_of_nuclear_and...

    The severity of the radioactive fallout was played down, and the release of a highly dangerous isotope during the fire, Polonium-210, was covered up at the time. [ 35 ] Partly because of this, consensus on the precise number of cancer deaths caused in the long term as a result of the radiation leak has changed over time as more information on ...
