Radiation measurement is necessary in many different places and for a variety of reasons. Meters are made subject to different requirements that can be found in Guide ST 1.9.
It must always be ensured, however, that the meter used is suitable for measuring the type of radiation in question and has been appropriately calibrated, and that the measurement result is sufficiently reliable for the purpose.
Radiation measurement is carried out for the purpose of individual monitoring of work conditions and employees, in activities that expose people to cosmic radiation, and in quality assurance of the use of radiation in health care and the determination of patient doses. In addition to radiation measurements, computational methods are also used to determine radiation exposure.
