Dosimeter `` Rook '' (DKG-03D).

Dosimeters, radiometers, roentgenometers and other similar devices.The Rook dosimeter (DKG-03D) has been produced since 1999. Designed to measure the rate of the ambient dose equivalent H * (10) of gamma radiation; measurement of the ambient dose equivalent H * (10) of gamma radiation (operator's dose). Highly sensitive dosimeter, convenient for conducting radiation examinations. The measurement result and its error are indicated continuously from the moment of measurement start and are constantly updated. Thanks to sound signals with a frequency proportional to the dose rate, the device is also convenient for assessing the radiation situation. Properties: independent restart of dose rate and dose measurement; continuous measurement with constant refinement of the result; assessment of the radiation situation with loud sound signals (clicks), the frequency of which is proportional to the dose rate; measurement result with any required statistical error; fast automatic restart of the device when the dose rate changes more than 3.4u; indication of the statistical error during the entire measurement; indication of the unit of measurement; backlighting of the scoreboard; pocket size; high sensitivity; the ability to work with a headset. Technical characteristics: Measurement range: dose rate H * (10) 0.1 μSv / h 1.0 mSv / h dose H * (10) 1.0 μSv 100 Sv. Energy range of gamma radiation, 0.05 3.0 MeV. The limits of the permissible measurement error are ± [15 + 2.5 / N * (10)]%, where N * (10) is the measured value, μSv / h (μSv). Sensitivity 20,000 imp / μSv. The energy dependence of the sensitivity (relative to the effective energy 0.662 keV) is no more than 25%. Time to reach operating mode 5 sec. Power supply 2 AA elements. Operating time with a set of batteries 200 hours. The weight of the device is 0.2 kg.
