| Popis: | One of the activities of the International Organization for Standardization (ISO) is the preparation and revision of standards specifying the requirements for photon, beta and neutron reference radiations to be used in radiation protection for the calibration of personal and area dosemeters and for contamination monitors. The reference radiations are also specified for determining the response of the instruments as a function of radiation energy and angle of incidence. Radionuclide sources, X ray facilities, reactors and accelerators are utilised as radiation sources to cover the wide range of radiation types and energies The standards are intended to be applied by primary and secondary standard dosimetry laboratories, but information contained in the standards is widely applicable. The standards specify, in addition, fundamental requirements for an adequate characterisation of reference radiations and describe calibration procedures. The latter include the specification of phantoms (trunk, arm/leg, finger) for the calibration and type testing of personal dosemeters in terms of the operational quantities proposed by the ICRU. Conversion coefficients are provided for all the reference radiations. The present paper gives background information about the concepts of the calibration procedures, the choice of the reference radiations, and their dosimetry. The main features of the standards are described and illustrated by examples. |
