  2. Survey meter - Wikipedia

    en.wikipedia.org/wiki/Survey_meter

    This provided a real-time dynamic indication of the radiation rate, and the principle has found widespread use in Health Physics and as radiation Survey meter. An instrument which totalises the events detected over a time period is known as a scaler. This colloquial name stems from the early days of automatic counting, when a scaling circuit ...

  3. Radiation exposure - Wikipedia

    en.wikipedia.org/wiki/Radiation_exposure

    Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [ 1 ]

  4. Dosimetry - Wikipedia

    en.wikipedia.org/wiki/Dosimetry

    Radiation dosimetry in the fields of health physics and radiation protection is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both internally, due to ingested or inhaled radioactive substances, or externally due to irradiation by sources of radiation.

    en.wikipedia.org/wiki/Geiger_counter

    A Geiger counter (/ ˈ ɡ aɪ ɡ ər /, GY-gər; [1] also known as a Geiger–Müller counter or G-M counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.

  9. Film badge dosimeter - Wikipedia

    en.wikipedia.org/wiki/Film_badge_dosimeter

    The film emulsion is black and white photographic film with varying grain size to affect its sensitivity to incident radiation such as gamma rays, X-rays and beta particles. [2] After use by the wearer, the film is removed, developed, and examined to measure exposure. When the film is irradiated, an image of the protective case is projected on ...
