PCM100 alpha beta gamma surface contamination measuring instrument
PCM100 Surface Contamination Survey Meter
PCM100 alpha beta gamma surface contamination measuring instrument is mainly used for measuring radioactive surface contamination. It can simultaneously measure alpha, beta and gamma rays, with a sensitive total area of 45 cm 2. It can be used in pollution measurement of nuclear power plant, decommissioning of nuclear facilities, radioactivity laboratory measurement and surface pollution measurement of other radioactive sites. The instrument detector and main engine are integrated design, equipped with instrument box, easy to carry, easy to operate, excellent and reliable performance.
