dosimeter

(noun)

A dosimeter is a device used to measure a dose of ionizing radiation. These normally take the form of either optically stimulated luminescence (OSL), photographic-film, thermoluminescent (TLD), or electronic personal dosimeters (PDM).

Examples of dosimeter in the following topics:

  • Measuring Radiation Exposure

    • There are several ways of measuring doses from ionizing radiation, including personal dosimeters and ionization chambers.
    • There are a number of types of wearable dosimeters: quartz fiber, film badge, thermoluminescent, and solid state.
    • People use these dosimeters to keep track of exposure, typically if they expect to come in contact with radioactive substances as part of their jobs.

  • Dosimetry

    • Workers who come in contact with radioactive substances or who may be exposed to radiation routinely carry personal dosimeters .
    • In the United States, these dosimeters usually contain materials that can be used in thermoluminescent dosimetry or optically stimulated luminescence.
    • Outside the United States, the most widely used type of personal dosimeter is the film badge dosimeter, which uses photographic emulsions that are sensitive to ionizing radiation.
