Household gamma radiation dosimeter '' Quartz DRGB-90 ''.
Dosimeters, radiometers, roentgenometers and other similar devices.The household gamma radiation dosimeter "Quartz DRGB-90" has been produced by the Kyshtym Radio Plant since 1992. Designed to measure the equivalent (exposure) dose of photon-ionizing radiation and is used for individual operational monitoring by the population of the radiation situation in residential and work premises, as well as on the ground. The device provides: sound and light indication of the registered radiation; light signaling of exceeding the power level of the equivalent dose of external radiation of 29 μSv / h (2900 μR / h); measuring the dose rate of photon radiation. Technical characteristics: Measurement range of equivalent dose rate, μR / h - 10 ... 300, exposure dose rate, μR / h - 100 ... 3000. The basic relative error in measuring the dose rate in the range of 0 ... 30 μSv / h is ± 40%. Energy range of registered radiation, MEW - 0.06 ... 1.25. The time for establishing the operating mode is 15 s. Measurement time - 60 s. Supply voltage 4.5 V. Overall dimensions - 148x72x31 mm.
