1.4 Design and theory of operation

1.4.1 General information
The dosimeter is a mono-block construction with a built-in detector of gamma and beta
radiation, a printed-circuit board equipped with a circuit of the anode voltage formation, digital
processing, control, and indication, and batteries.
Gamma and beta radiation detector transforms radiation into the sequence of voltage
pulses; the number of pulses is proportional to the registered radiation intensity.
The circuit of the anode voltage formation, digital processing, control and indication provides:
- scaling and linear realization 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;
- measurement of photon-ionizing radiation DE by means of measurement of a general
number of pulses from the detector outlet;
