Dosemeter DRG-01T (DRG01T, DRG-01-T, DRG 01 T, DRG 01T, DRG01-T, DRG01 T)
 
Dosemeter DRG-01T is designed to measure the exposure dose in the workplace, and in adjacent areas in enterprises that use radioactive substances and other sources of ionizing radiation, in the buffer zone and the surveillance zone.
In addition, the monitor can be used to monitor the effectiveness of shielding, radiation and radioactive waste packages, as well as the measurement of the exposure dose during the occurrence, course and aftermath of emergencies.
Dosimeter used for operational control group exposure dose of radiation safety services workers, flaw detection laboratories, sanitary-epidemiological stations, etc.
The device features easy operation, versatility, features and modern design.
Periodic checking of the device monitor DRG-01T conducted at the request of the consumer regional bodies or organizations eligible for instrument calibration.
 
Technical characteristics of the devices dosemeter DRG-01T:
 
Dosimeter is designed to work in:
- Ambient temperature - from -10 ° C to +40 ° C;
- Relative humidity - up to 90% at +30 ° C;
- Atmospheric pressure - from 84kPa to 106.7 kPa;
- In the presence of background neutron radiation;
- In a soiling of radioactive substances;
- In areas with low light and in the dark;
- In constant magnetic fields of strength 318.31 A / m;
Dosemeter DRG-01T provides a measurement of the exposure dose in the range of photon energies - from 8fDzh to 480fDzh (from 0.050 MeV to 3.0 MeV);
Dosimeter measures the exposure dose in two modes:
- Mode - "Search";
- Mode - "Measurement";
Dosemeter DRG-01T in mode "Measurement" provides a measurement of the exposure dose in the range - 0,010 mR / hr to 9,999 R / h with a breakdown on the entire range of two sub-bands:
I - 0,010 mR / hr to 9,999 mR / hr;
II - 0,010 R / hr to 9,999 R / hr;
In mode "Search" dosemeter measures the radiation exposure dose range - from 0.10 mR / h to 99.99 p / h with a breakdown on the entire range of two sub-bands:
I - 0.10 mR / h to 99.99 mR / hr;
II - 0.10 p / h to 99.99 p / h;
Time measurement device dosemeter DRG-01T:
- In the mode of "Measure" - no more than 20 s;
- In the "Search" - no more than 2c;
Warm-up time - no more than 4s;
Maximum permissible error of measurement (for a 95% confidence interval) at any point on the calibration sub-band power of the 2nd level of cesium-137 and normal conditions of use is:
- In the mode of "Measure" - ± (15 + (0.5 x / X))%;
- During operation "Search" - ± (30 + (1.0 x / X))%;
where X - the exposure dose in units of the corresponding sub-band measurements (mR / h or R / h) x - a unit dimension of the corresponding sub-band (1mR / h or 1P / h);
Footnote. Normal climatic conditions of the instrument dosemeter DRG-01T match:
- Ambient temperature - 20 ° C ± 5 º C;
- Relative humidity - 30% to 80%;
- Atmospheric pressure - from 84kPa to 106kPa;
The values ​​of the influence quantities characterizing the climate impacts the operating conditions of the instrument dosemeter DRG-01T, are:
- Ambient temperature - from -10 ° C to +40 ° C;
- Relative humidity - up to 90% at +30 ° C;
- Atmospheric pressure - from 84kPa to 106.7 kPa;
The values ​​of the influence quantities characterizing the climatic and mechanical effects in the limiting conditions of transport device dosemeter DRG-01T are:
- Ambient temperature - from -50 ° C to +50 ° C;
- Relative humidity - 95% at +30 ° C;
- Atmospheric pressure - from 84kPa to 106.7 kPa;
- Transport shaking:
- The number of beats per minute - 80-120;
- The maximum speed - 30 m / s 2, the duration of exposure of 1 hour;
Additional instrument error DRG-01T monitor the temperature change in the working conditions of use does not exceed ± 3% at 10 ° C of the dosemeter under normal conditions;
Additional instrument error of changes in the relative humidity of the air in the working conditions of use does not exceed ± 15% of the dosemeter under normal conditions;
Dosimeter device DRG-01T retains basic measurement error within the rules, after the climatic and mechanical effects in the limiting conditions of transport;
As the radiation detectors used four gas-discharge counters GMS-20 and two counters SI 34g (40g SI) with corrective lead filter to align the energy dependence of sensitivity;
The normal operating position of the instrument dosemeter DRG-01T, corresponding to the maximum sensitivity - the radiation direction perpendicular to the plane of the detector (the geometric center of the detectors located on the back cover of the dosemeter);
Changing the dosemeter at a constant dose rate depending on the energy of the detected radiation in the range of 0.05 MeV-3 0MeV in the normal position of the dosemeter does not differ by more than ± 25% of the value obtained from the radiation source of the radionuclide cesium-137 (660keV);
Changing the device monitor DRG-01T (anisotropy), depending on the angle of ionizing, radiation in the range of ± 45 ° relative to the direction of maximum sensitivity is less than;
- 20% - for the emission of radionuclides cesium-137 and cobalt-60 (660keV and 1.25 MeV);
- 30% - for radionuclide radiation thulium-170 (84keV);
When the angle of incidence of ± 90 °, does not exceed:
- 50% - for the emission of radionuclides cesium-137 and cobalt-60;
- 80% - for radionuclide radiation thulium-170;
Maximum allowable radiation dosemeters devices DRG-01T corresponds exposure rate 1000r / h, while in any mode of operation on the scale of the digital display shows overflow (indicates "P");
At the end of radiation dosemeter keeps working;
The power supply in the device monitor DRG-01T uses a galvanic cell type "Corundum";
Current consumption from the power supply when power level dose for 75% of the maximum value in any sub-band measurement provides continuous operation of the dosemeter for at least 24 hours, and the instability of the testimony does not exceed ± 10%;
At levels of external radiation background not exceeding 50mkR / h unit dosemeter DRG-01T allows continuous operation for at least 100 hours;
Calculated MTBF dosemeter - not less than 5000 hours;
Service life dosemeter DRG-01T to overhaul - at least 8 years;
Overall dimensions of the dosemeter - do not exceed 160x76x46mm;
Weight dosemeter (power supply) - not more than 0.5 kg;
The manufacturer guarantees that the quality of the instrument dosemeter DRG-01T technical requirements specifications provided the customer terms and conditions of storage, transportation, installation, operation, and its specified operational documentation.
