4 Design and principle of operation
4.1 General information
The dosimeter is a mono block construction with a built-in detector of gamma
and beta radiation (Geiger-Muller counter), a printed-circuit board equipped with
electronic components, and batteries.
The operation principle of the dosimeter is based on transformation of radiation
by Geiger-Muller counter into the sequence of voltage pulses; the number of pulses is
proportional to the registered radiation intensity.
The power for operation is supplied by two AAA batteries.
4.2 Design description
The dosimeter is designed as a flat square plastic body with rounded corners.
