1.4.2 Basic operation of the radiometer
The radiometer is a mono-block construction with:
- the detector of gamma and beta radiation;
- the printed-circuit board with the circuit of the anode voltage formation, the
circuit of digital processing, control, and indication and the module of
Bluetooth radio channel;
- the batteries.
The gamma and beta radiation detector built on the basis of СБМ-20-1 Geiger-
Muller counter, transforms radiation into the sequence of voltage pulses; the number
of pulses per unit of time is proportional to the registered radiation intensity.
The circuit of the anode voltage formation and the circuit of digital processing,
control and indication provide:
- generation and regulation of the detector anode voltage;
- scaling and linearization of the detector counting response;
- measurement of photon-ionizing radiation DER and surface beta-particles flux
density by means of measurement of an average pulse frequency from the detector outlet;
- real time measurement;
