1.4.2 Basic operation of the radiometer
The radiometer is a monoblock, which contains:
−
BETA-2-1 Geiger-Mueller counter;
−
printed circuit board with circuits of the anode voltage generation, digital
processing, control and indication and the module of Bluetooth radio channel;
−
batteries;
BETA-2-1 Geiger-Mueller counter, sensitive to alpha, beta and gamma rays,
converts radiation into a sequence of voltage pulses, the amount of which per unit
of time is proportional to the radiation intensity.
Circuits of the anode voltage generation, digital processing, control and
indication perform:
- generation and stabilization of the counter's anode voltage;
- scaling and linearization of the counter's counting response;
