    Ionizing radiation (US, ionising radiation in the UK), ... Outside the nucleus, free neutrons are unstable and have a mean lifetime of 14 minutes, 42 seconds.

  3. Radiation - Wikipedia

    en.wikipedia.org/wiki/Radiation

    The probability of ionizing radiation causing cancer is dependent upon the absorbed dose of the radiation and is a function of the damaging tendency of the type of radiation (equivalent dose) and the sensitivity of the irradiated organism or tissue (effective dose).

  4. Ionization - Wikipedia

    en.wikipedia.org/wiki/Ionization

    It is also used in radiation detectors such as the Geiger-Müller counter or the ionization chamber. The ionization process is widely used in a variety of equipment in fundamental science (e.g., mass spectrometry) and in medical treatment (e.g., radiation therapy). It is also widely used for air purification, though studies have shown harmful ...

    en.wikipedia.org/wiki/Radiation_protection

    Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". [1]

  6. Acute radiation syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_radiation_syndrome

    Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.

  7. Radiation hardening - Wikipedia

    en.wikipedia.org/wiki/Radiation_hardening

    Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...
