Mobile in-situ waste assay system with Stirling-cooled HPGe
Mobile system for radioactive waste assay by high-resolution gamma spectrometry, including free-release decommissioning waste. An IDM-200-V with a very large HPGe detector and a modular collimator system sits on the ISO-CART-II cart, and the ISOPLUS (ISOTOPIC) software reports the result in grams or activity. Supplied factory calibrated and ready to go.
