Device Prospecting Scintillation SRP-97

The SRP-97 device is a direct analogue of the exploration scintillation SRP-68-01 device for its functional purpose and scope.

CHARACTERISTICS

The range of measurement of the exposure dose rate (DER) of gamma radiation of radium-226 radionuclide consists of the following sub-ranges:
- from 0 to 30 μR / h;
- from 0 to 100 μR / h;
- from 0 to 300 μR / h;
- from 0 to 1000 μR / h;
- from 0 to 3000 μR / h.
The limits of the permissible basic error of measurement of DER of gamma radiation of radium-226 radionuclide are not more than ± 15%.

NOTE

In the initial section of each subrange up to 20% of the measurement limit, the basic error is not standardized.
A subrange with a measuring range of 30 μR / h is not checked at the manufacturer.
The range of the device for measuring the average count rate of registered gamma rays consists of the following subranges:
- from 0 to 100 s ^-1 ;
- from 0 to 300 s ^-1 ;
- from 0 to 1000 s ^-1 ;
- from 0 to 3000 s ^-1 ;
- from 0 to 10,000 s ^-1 .
The limit of permissible basic error of the device for measuring the average count rate of registered gamma-quanta is not more than ± 10%.
In the initial section of each subrange up to 20% of the measurement limit, the basic error is not standardized.
The maximum permissible additional error of DER measurement when the ambient temperature changes from minus 20 to 50 ° C does not exceed ± 5%.
The maximum permissible additional error of DER measurement when the orientation of the detection unit in the Earth’s magnetic field does not exceed ± 2.5%.
The energy range of the recorded gamma rays from 35 to 3000 keV.
The time to establish the operating mode is not more than 1 min
The time of continuous operation is at least 8 hours. The power supply resource from the battery ensures the operation of the device for at least 50 hours

Subject to annual verification.
