Abstract. Measuring the activity of radionuclides is one of the most popular directions in the field of ionizing radiation measurements. The fact that ensuring the unity and reliability of measu­rements of the activity of radionuclides is the most important task is obvious. Radionuclide sources of ionizing radiation for metrological purposes are necessary for the calibration and graduation of radiometers and spectrometers and are also used as control sources. VNIIFTRI develops and manu­factures various types of metrological sources: point sources, surface sources, simulators of radio­actively contaminated environmental objects, which, in turn, are divided into solid-state and bulk sources. The use of these sources avoids a significant increase in the error of measuring instruments.

Keywords: metrological source, special measure of activity, ionizing radiation, metrology, spectrometry and radiometry, reference source, measurement error.
