Dosimeter DSM-20LS
Dosimeter DSM-20LS offers detection of beta, and gamma radiation and measures dose equivalent rates from 0.01 μSv/h to 10 mSv/h. It utilizes ore-containing materials for radioactive detection and incorporates a cobalt source for enhanced accuracy. Includes a built-in gamma and beta-sensitive Geiger-Muller counter for reliable measurement. Equipped with a magnifying tube for quick identification and localization of gamma and beta radiation.
