• Notes

• Health and safety dosimeter/Radiometer/Geiger Counter/Radiation Detector instrument designed to measure the equivalent dose of external gamma radiation and display the result on the digital display and qualitative assessment of the intensity of gamma radiation with a sound; the algorithm of work is 35-40 second countings, up to 10 second indication of result and counting again; based on built-in СБМ20 Geiger-Muller tube.

  Automatic switching for the three sub-bands of measurements: measurement range of the equivalent dose rate of external gamma radiation is from 0.10 µSv/h to 999 µSv/h divided into three automatic ranges.
  Limits of the permissible basic relative error of the device dosimeter: no more than ± 25 % at any point of the operating range when grading over the exemplary source of the second disharge of cesium-137 under normal operating conditions; limits of the admissible additional error of the device, caused by change in the ambient temperature in the range from -10 °C to 40 °C, ± 10 % for every 10 °C; limits of the allowed additional error caused by a change in the supply voltage from the rated voltage within the limits of 4.5 V ± 0.45 V: no more than ± 5 %.

  The energy dependence in the energy range is from 0.04 MeV to 1.3 MeV; the time of continuous operation with instability of indications no more than ± 5 %: not less than 8 hours; measurement time depending on the selected range 3-5 second, 5-7 second or 35-37 second; when the production of the dosimeter DBGB-01S is released from production, it was subject to obligatory initial state verification, as indicated in the operating manual.
