Blocks of detection are intended to measure the ambient power of the equivalent dose H * (10) of gamma radiation and are used with free-running devices, and systems monitoring the radiological situation.
Output signal corresponds to the standard interface:
• RS – 485 – detection unit BDBG-200.23PD;
The content and format of the data 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
of 0.1 mSv / h to 10 Sv / h:
3. The measuring range is divided into two, automatically switching, sub-ranges:
– Subrange “sensitive” channel – from 0.1 mZv • h-1 to 2.0 mZv • h-1;
– Subrange “rough” channel – from 0.5 mZv • h-1 to 10 Zv • h-1.
4. Sensitivity *: “sensitive” channel – (4,4 ± 0,44) with 1 / Zv • h-1
“Rough” channel – (5,0 ± 2,0) with 1 / mZv • h-1.
5. Limits of basic relative error of the block – ± 20%.
6. Energy dependence * in the range from 0,06 to 1,25 MeV – no more than 30%
7. Algorithm for processing measuring data – a method of “moving average”. Integration time is 40 seconds. Exposure – 1.
8. Dimensions of the unit: diameter is 60 mm, length is 300 mm.
9. Weight is not more than 0,5 kg.
10. Output Connector Type: 2RMGD24.
* Radiation of radionuclide cesium-137 (662 keV).
ELECTRICAL CHARACTERISTICS
1. Power supply – is DC voltage from 8,0 to 42,0 V, consumed current is less than 10 mA.
2. The total wire of power supply circuit is not electrically connected to the outer casing of the detection unit.
