The specific of metrological support for different types of dosemeters are considered. Gamma-ray sensors are commonly used for measuring radiation doses as also the fluid levels in the industry. Typically, the 60Co or 137Cs isotopes as the radiation source are applied. For instance, in the USA, such detectors are beginning to be used as part of the Container Security Initiative . Problems of their metrological assurance are becoming more general.
The article deals with the development of the reference means of support and metrological insurance required for metrological verification and calibration of beta and gamma radiation dosimeters. The latter are extremely necessary for dosimetric measurements of radiation characteristics in the field of radiation safety, radiation diagnosis and therapy.
