Dosimeter-radiometer "Expert".
Dosimeters, radiometers, roentgenometers and other similar devices.Dosimeter-radiometer "Expert" has been produced since 1988 in professional and domestic versions. Designed to determine the equivalent dose rate of photon (gamma) radiation and beta-radiation flux density from contaminated surfaces in everyday life, at work and in the banking sector. Measurement range of equivalent dose rate, μSv / h 0.1-500. The range of photon energies when measuring the dose rate, MeV 0.06-1.25. Basic relative error in determining the dose rate,% ± 30. Energy dependence when measuring the dose rate,% ± 50. Measurement range of beta-radiation flux density from contaminated surfaces for strontium-90, yttrium-90 or cesium-137, part / s. cm2 0.3-500. The lower limit of the energy of the detected beta radiation MeV is 0.156. Power supply - 6F22 battery. Dimensions, mm - 192x64x40. Weight, kg - 0.3.
