1.4 Design and theory of operation
1.4.1 The dosimeter comprises the following main blocks and modules:
- radiation detector;
- microprocessor;
- LCD;
- secondary power supply;
- IR-transceiver;
- non-volatile memory.
The block diagram of the dosimeter is shown in Figure 1.1.
Figure 1.1 – Block diagram of the dosimeter
A Geiger-Muller tube with a filter for spatial-energy formation of sensitivity, which
converts photon radiation quanta to electric pulses, is used as a radiation detector. The
detector has a high-voltage power supply.
