Abstract. This article deals with methods for measuring the characteristics of ionizing radiation in solving problems of radiation monitoring of the environment, industrial premises, sanitary protection zones, human pollution control using measurement techniques certified in the prescribed manner. The types of measuring instruments involved in the measurement of various quantities are listed. The main objects of measurements used in radiation monitoring of the environment, control of surface contamination and human contamination are named. The metrological characteristics (measured quantities) of measuring instruments are compared with the metrological characteristics of real measurement objects. A number of necessary established metrological characteristics for radiometric and spectrometric measuring instruments for the successful use of a measuring instrument in solving one or another problem of radiation measurements is indicated. An example from a real work is considered, in which the method of mathematical modeling when calculating additional metrological characteristics showed a significant discrepancy with the real data obtained during the experiment.
Keywords: spectrometry, radiometry, alpha-, beta-, gamma-emitting radionuclide, environmental monitoring, mathematical modeling.
