Scintillation dosimeter `` DRGZ-02 ''.
Dosimeters, radiometers, roentgenometers and other similar devices.The scintillation dosimeter "DRGZ-02" has been produced since 1975. The dosimeter is designed to measure the exposure dose rate of X-ray and gamma radiation in laboratory and industrial conditions. The range of measured rates of exposure doses of X-ray and gamma radiation of the dosimeter is from 0 to 2.52 * 10-7 A / kg (from 0 to 100 μR / s). This range is divided into the following subranges: from 0 to 0.1 μR / s, from 0 to 0.3 μR / s, from 0 to 1.0 μR / s, from 0 to 3.0 μR / s, from 0 to 10.0 μR / s, from 0 to 30.0 μR / s, from 0 to 100.0 μR / s. The range of effective energies of quanta of the registered X-ray and gamma radiation is from 3.2 * 10-15 to 480 * 10-15 J (from 20 to 3000 keV). The limits of the basic measurement error of the exposure dose rate are divided into subranges: from 0.1 to 0.3 μR / s 15% (other subranges are 10%). The energy dependence of the device when measuring the energy of X-ray and gamma radiation in the range from 20 to 3000 keV is 25% relative to the readings of the radiation energy of 1250 keV (cobalt-60). The dosimeter has radiation immunity to fast neutrons, which ensures the measurement of the dose rate of X-ray and gamma radiation at a fast neutron flux of 20 neutrons / cm2 * s with an additional error not exceeding +/- 1% relative to the maximum permissible dose rate of X-ray or gamma -radiation 0.8 μR / s. The radiation resistance of the dosimeter is determined by the limiting value of the absorbed dose in the scintillating plastic of the detecting unit and is not less than 1000 J / kg. The dosimeter is powered by a 220 V network or 12 mercury-zinc elements RC-85. Consumption current 10 mA. The dimensions of the control panel are 200x160x95 mm. The dimensions of the detecting unit are 50x330 mm. Remote control weight 2.3 kg, detection 0.7 kg. Information and photos from the site: http://forum.rhbz.org/
