Blocks of detection are intended for measuring the ambient power of the equivalent dose H*(10) of gamma radiation and are used with free-running devices(BDBG-200UD), and radiation monitoring systems.
Output signal corresponds to the standard interface:
• RS – 485 – detection unit BDBG-200 PD
• RS – 422 – detection unit BDBG-200 DD
The contents and the format of the data are defined in the report of the information exchange DiBUS (www.doza.ru)
1. Energy range of detected gamma radiation is from 0,06 to 3,0 MeV.
2. Measuring range of ambient power of the equivalent dose H*(10) of gamma radiation is
from 0.1 mkZv / h to 10 Zv / h:
3. measuring range is divided into two, automatically switching, sub-ranges:
– Subrange “sensitive” channel – from 0.1 mkZv • h-1 to 2.0 mkZv • h-1;
– Subrange “rough” channel – from 0.5 mSv • h-1 to 10 Sv • h-1.
4. Sensitivity *: “sensitive” channel – (4,4 ± 0,44) c-1/mk3v∙h-1
“Rough” channel – (5,0 ± 2,0) c-1/mk3v∙h-1.
5. Limit of the basic relative error of the block is ± 20%.
6. Energy dependence * in the range from 0,06 to 1,25 MeV is no more than 30%
7. Algorithm for processing measuring data is a method of “moving average”. Integration time is 40 seconds. Exposure – 1.
8. Dimensions of the unit: diameter is 50 mm, length is 300mm. (with an output connector 2RMGD24, diameter is 60 mm, length is 300 mm.).
9. Weight is not more than 0,5 kg.
10. Type of an output connector (on request): RS-10, ОNZ-10, 2RMGГ18, 2RMGD24.
* Radiation of radionuclide cesium-137 (662 keV).
ELECTRICAL CHARACTERISTICS
1. Power supply – DC voltage from 8,0 to 42,0 V (detection unit BDBG-200UD – 5,0 V). Consumed current is not more than 10 mA.
2. Common cable of the power supply circuit is not electrically connected to the outer casing of the detection unit
