Dosimeter (β and γ) LDSM-A10 features Ore containing materials for radioactive detection and Cobalt source for electronic accelerator irradiation place radiation detection with Energy ranges of X and Gamma radiation up to 40 KeV to 3.0 MeV and Beta radiation up to 0.5 to 3.0 MeV. Automatic failure detection function, measures gamma and beta radiation dose rate from the background to extra levels with digital LCD backlight display for specifies units of measurement with low battery indication, measurement errors, surface soft and hard beta-particles flux density, threshold level and real time. Magnifying tube has quick detection and localization of gamma and beta radiation sources within seconds and Built-in gamma, beta sensitive Geiger-Muller counter.
