  2. Radiation - Wikipedia

    en.wikipedia.org/wiki/Radiation

    Infrared or red radiation from a common household radiator or electric heater is an example of thermal radiation, as is the heat emitted by an operating incandescent light bulb. Thermal radiation is generated when energy from the movement of charged particles within atoms is converted to electromagnetic radiation.

  3. Radiation exposure - Wikipedia

    en.wikipedia.org/wiki/Radiation_exposure

    Electromagnetic radiation consists of photons, which can be thought of as energy packets, traveling in the form of a wave. [4] Examples of electromagnetic radiation includes X-rays and gamma rays (see photo "Types of Electromagnetic Radiation"). [4] These types of radiation can easily penetrate the human body because of high energy. [4]

  4. Background radiation - Wikipedia

    en.wikipedia.org/wiki/Background_radiation

    Background radiation is a measure of the level of ... feature of everyday life in both working and public environments. ... by the background radiation. An example of ...

  5. Gamma ray - Wikipedia

    en.wikipedia.org/wiki/Gamma_ray

    There is a small increase in the dose, due to naturally occurring gamma radiation, around small particles of high atomic number materials in the human body caused by the photoelectric effect. [24] By comparison, the radiation dose from chest radiography (about 0.06 mSv) is a fraction of the annual naturally occurring background radiation dose. [25]

  6. Electromagnetic radiation and health - Wikipedia

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

    Dielectric heating from electromagnetic radiation can create a biological hazard. For example, touching or standing around an antenna while a high-power transmitter is in operation can cause burns. The mechanism is the same as that used in a microwave oven. [6]

  7. Background radiation equivalent time - Wikipedia

    en.wikipedia.org/wiki/Background_radiation...

    Background radiation level is widely used in radiological health fields as a standard for setting exposure limits. [1] Presumably, a dose of radiation which is equivalent to what a person would receive in a few days of ordinary life will not increase their rate of disease measurably.

  8. Ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Ionizing_radiation

    For example, ionizing radiation is one cause of chronic myelogenous leukemia, [22] [23] [24] although most people with CML have not been exposed to radiation. [23] [24] The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. [citation needed]

  9. Non-ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Non-ionizing_radiation

    A common example of such radiation is sunlight, which is thermal radiation from the Sun's photosphere and which contains enough ultraviolet light to cause ionization in many molecules and atoms. An extreme example is the flash from the detonation of a nuclear weapon , which emits a large number of ionizing X-rays purely as a product of heating ...
