  2. Rad (radiation unit) - Wikipedia

    en.wikipedia.org/wiki/Rad_(radiation_unit)

    That model calculates an effective radiation dose, measured in units of rem, which is more representative of the stochastic risk than the absorbed dose in rad. In most power plant scenarios, where the radiation environment is dominated by X-or gamma rays applied uniformly to the whole body, 1 rad of absorbed dose gives 1 rem of effective dose. [5]

  3. 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.

  4. Geiger counter - Wikipedia

    en.wikipedia.org/wiki/Geiger_counter

    "Geiger counter" is often used generically to refer to any form of dosimeter (or, radiation-measuring device), but scientifically, a Geiger counter is only one specific type of dosimeter. It detects ionizing radiation such as alpha particles , beta particles , and gamma rays using the ionization effect produced in a Geiger–Müller tube ...

  5. Radiation detection - Wikipedia

    en.wikipedia.org/wiki/Radiation_detection

    The following Radiological protection instruments can be used to detect and measure ionizing radiation: Ionization chambers; Gaseous ionization detectors; Geiger ...

  6. Dosimeter - Wikipedia

    en.wikipedia.org/wiki/Dosimeter

    A radiation dosimeter is a device that measures dose uptake of external ionizing radiation. It is worn by the person being monitored when used as a personal dosimeter, and is a record of the radiation dose received.

  7. Counts per minute - Wikipedia

    en.wikipedia.org/wiki/Counts_per_minute

    The continuous current ion chamber instrument can easily measure dose but cannot measure counts. However the Geiger counter can measure counts but not the energy of the radiation, so a technique known as energy compensation of the detector tube is used to produce a dose reading. This modifies the tube characteristic so each count resulting from ...

  8. Gray (unit) - Wikipedia

    en.wikipedia.org/wiki/Gray_(unit)

    The gray measures the total absorbed energy of radiation, but the probability of stochastic damage also depends on the type and energy of the radiation and the types of tissues involved. This probability is related to the equivalent dose in sieverts (Sv), which has the same dimensions as the gray.

  9. Survey meter - Wikipedia

    en.wikipedia.org/wiki/Survey_meter

    Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation. The hand-held survey meter is probably the most familiar radiation measuring device owing to its wide and visible use.
