Sovet Dosimeter DP-22-B. Militaria USSR (ДП-22-В) dosimeter in working condition DP-22B kit DP-22B personal dosimeters Meter dose DP-22B DP-22B, DP-22B kit dosimeters for measuring the exposure dose of gamma radiation in the range of 2 - 50 R. The set includes: charger ZD-5 and 50 meters dose DCT-50A. DP-22B kit dosimeters consists of 50 individual dosimeters DCT-50A and charger ZD-5. Dosimeter DCT 50A is designed as pens ( "pen") and consists of an ionization chamber, electroscope, the condenser and the microscope in the contact group duralumin housing. When exposed to ionizing radiation of the charged volume of the ionization chamber, the walls of which are made of a conductive plastic tissue-equivalent, the current occurs, which reduces the potential of the camera and its associated capacitor. When this thread electroscope, supplied with the potential of the capacitor is deflected and its deflection is measured with a microscope on a scale calibrated in roentgens. The scale has 25 divisions, division value 2 R. In order to ensure the linearity of the scale the charging potential of the ionization chamber is selected in the range of 180-250 V. A contact group dosimeter is its charge with the charger ZD-5 or any other DC voltage source, having a smooth adjustment voltage of 180 to 250; after charging the contact group protects the monitor from the discharge. The charger ZD-5 contains two power supply 145U (replaced by any battery 1.5V), power generating circuit DC voltage of 250 V, a variable resistor to set the desired voltage and for dosimeter charger jack. Two new elements 145U provides charger operation for 30 hours. To charge the dosimeter is inserted into the contact group in the battery slot on the product; with pressure on the monitor to the central electrode of the ionization chamber is served plus an external electrode-less. The dosimeter is set by its scale to zero. Specifications BF-22B: Measuring range of exposure dose of gamma radiation at a dose rate ot0,5 to 200 R / h, X 0-50 Energy range of gamma radiation, MeV 0.1 -2.0 Self-discharge of the dosimeter under normal conditions for 24 hours, divisions, does not exceed 2 The main permissible error of measurement of doses of gamma radiation 60Co in normal conditions,% of full scale value does not exceed ± 10 Energy dependence of sensitivity in the range of energies of the gamma radiation of 0.1 to 2.0 MeV with respect to testimony during irradiation 60Co gamma radiation,%, no more than ± 40 The number of charging cycles is not less than 10,000 Operating temperature 0 C -40 - +50 Humidity% at + 300 ° C up to 90 Overall dimensions, not more: -dozimetra holder 19h132 -komplekta in case 360h152h180 -zaryadnogo device ZD-5 110h135h140 Weight, g, no more than: -dozimetra 35 -komplekta case in 5500 -zaryadnogo device (no power supply) 1400 Currently set not discharged!
