  2. Radioactive contamination - Wikipedia

    en.wikipedia.org/wiki/Radioactive_contamination

    The hazards to people and the environment from radioactive contamination depend on the nature of the radioactive contaminant, the level of contamination, and the extent of the spread of contamination. Low levels of radioactive contamination pose little risk, but can still be detected by radiation instrumentation.

  3. Bioremediation of radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Bioremediation_of...

    The presence of radioactive waste in the environment may cause long-term effects due to the activity and half-life of the radionuclides, leading their impact to grow with time. [2] These particles exist in various oxidation states and are found as oxides , coprecipitates , or as organic or inorganic complexes, according to their origin and ways ...

  4. Environmental radioactivity - Wikipedia

    en.wikipedia.org/wiki/Environmental_radioactivity

    The caesium isotopes in the fallout have had an effect on farming. A large amount of caesium was released during the Goiânia accident where a radioactive source (made for medical use) was stolen and then smashed open during an attempt to convert it into scrap metal. The accident could have been stopped at several stages; first, the last legal ...

  5. Radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Radioactive_waste

    The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into 3 categories: low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity; intermediate-level waste ...

  6. Radioecology - Wikipedia

    en.wikipedia.org/wiki/Radioecology

    The practice consists of techniques from the general sciences of physics, chemistry, mathematics, biology, and ecology, coupled with applications in radiation protection. Radioecological studies provide the necessary data for dose estimation and risk assessment regarding radioactive pollution and its effects on human and environmental health. [1]

    A major radioactive contamination threat to the Columbia River should be removed at the Hanford nuclear site before the end of summer. Hanford workers have started to pump contaminated water from ...

  8. Radium and radon in the environment - Wikipedia

    en.wikipedia.org/wiki/Radium_and_radon_in_the...

    Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.

  9. Uranium in the environment - Wikipedia

    en.wikipedia.org/wiki/Uranium_in_the_environment

    Mining is the largest source of uranium contamination in the environment. [1] Uranium milling creates radioactive waste in the form of tailings, which contain uranium, radium, and polonium. Consequently, uranium mining results in "the unavoidable radioactive contamination of the environment by solid, liquid and gaseous wastes". [13]
