  • EFRD Rad XP series are designed to provide versatile tools for online/offline measurement and analysis of gamma spectrum anywhere, including marine and freshwater, ground and aerospace.
    Rad XP follows SI’s state-of-the-art Multi-Channel Analyzer (MCA) technology to provide stable dose rate measurement as well as discrimination of natural and artificial radiation. It especially features low noise ADC, fast and flexible MCA, low power consumption, user friendly interfaces and high system extendibility. It has improved user friendly interfaces through extensive experience of user applications.

    Rad XP-UW (UnderWater) is a complete and integrated spectroscopy solution for underwater radiation monitoring in fresh and marine, which is compatible with various type/size of detectors. It consists of Detection unit (HAMPack series) and Local controller unit, which is the hardware and software necessary to acquire / process spectrum, calculate radiation parameters and control the system.
    Measured data, including system status, spectra and dose rate information, are transmitted via Wi-Fi, GSM, CDMA, 3G/4G wireless to remote users and allows users to integrated situation management in more effective way.
