Description

Application

Specification

Compact device designed for measurements of gamma and X-radiation ambient equivalent dose (and dose rate), as well as for measurement the flux density of beta particles from contaminated surfaces.
There is 'search mode' for measure count rate in counts per second (cps).

Device operating principle is based on the process of count rate measurement of pulses generated in Geiger-Muller counter tube under the influence of X, gamma and beta radiation.
Count rate is converted automatically into physical values. Energy compensating filter allows correcting energy dependence of sensitivity efficiently in entire energy range of photon radiation.
Microprocessor-based unit is responsible for controlling the radiation monitor operating modes, calculations, storing and displaying measurement results and for self-checking function.
To easy use during the measurements of surface contamination the monitor can be hold in the bar.
