GammaSight / Coming Soon: Pocket-Sized Radiation Detector and Multi-Channel Analyzer

GammaSight GammaSight™ is a rugged, pocket-sized radiation detector and multi-channel analyzer that utilizes an Android operating system for user interface, data storage, and transmission. The small, lightweight GammaSight™ detector provides radionuclide identification and spectrum analysis in a very portable package. The detector module works with users’ standard Android smartphones and tablets via wireless Bluetooth connectivity for visual display of measurement results, map overlay, text messaging, data storage, and follow-up analysis. This approach allows for the development of customized applications to address specialized needs.
