  2. Radiation damage - Wikipedia

    en.wikipedia.org/wiki/Radiation_damage

    Ionizing radiation is generally harmful and potentially lethal to living things but can have health benefits in radiation therapy for the treatment of cancer and thyrotoxicosis. Its most common impact is the induction of cancer with a latent period of years or decades after exposure.

  3. Safe handling of carcinogens - Wikipedia

    en.wikipedia.org/wiki/Safe_handling_of_carcinogens

    Ideally carcinogenic substances should be avoided by substitution with less hazardous substances. Alternate form of carcinogenic substances may also be used to minimize the risk of exposure. In the case of carcinogens which pose a danger through inhalation, pastes or pellets can be used to avoid the possibility of airborne dust.

    A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs.. Strange as it sounds, the lighter-than-air element that gives ...

  5. Helium - Wikipedia

    en.wikipedia.org/wiki/Helium

    Inhaling helium can be dangerous if done to excess, since helium is a simple asphyxiant and so displaces oxygen needed for normal respiration. [28] [186] Fatalities have been recorded, including a youth who suffocated in Vancouver in 2003 and two adults who suffocated in South Florida in 2006.

  6. Inert gas asphyxiation - Wikipedia

    en.wikipedia.org/wiki/Inert_gas_asphyxiation

    The method of suicide based on self-administration of helium in a bag, a colloquial name being the "exit bag" or suicide bag, has been referenced by some medical euthanasia advocacy groups. [36] Originally, such bags were used with helium, and 30 deaths were reported with use of them from 2001 to 2005, and another 79 from 2005 to 2009.

  7. Asphyxiant gas - Wikipedia

    en.wikipedia.org/wiki/Asphyxiant_gas

    Large-scale natural release of gas, such as during the Lake Nyos disaster in which volcanically-released carbon dioxide killed 1,800 people. [6] Release of helium boiled off by the energy released in a magnet quench such as the Large Hadron Collider or a magnetic resonance imaging machine. Climbing inside an inflatable balloon filled with ...

  8. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    In 2011, the WHO/International Agency for Research on Cancer (IARC) has classified radio frequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma and acoustic neuroma associated with wireless phone use. The group responsible for the classification did not quantify the risk.

  9. Medical gas therapy - Wikipedia

    en.wikipedia.org/wiki/Medical_gas_therapy

    The dry air on the Earth we inhale consists of 78.8% nitrogen, 20.95% oxygen and 0.93% argon. Heliox therapy is substitution of nitrogen with helium. Helium itself has no pharmacological value, it does not react in the body. Its only purpose is to make the flow less turbulent and help oxygen to get into the lungs.
