RadSolver - A High Energy Resolution RIID

RadSolver is based on ScintiClear detector- a new high-performance SrI2(Eu)-based gamma-sensitive scintillator. With excellent energy resolution across 20keV – 3MeV energy range, high stopping power, and the absence of internal activity, ScintiClear heralds a new era in rapid and accurate identification of complex isotope mixtures in small volumes and shielded containment. RadSolver is a rugged RIID with state-of-the-art nuclide identification software, approved by the IAEA community and widely used in demanding environments all over the world.
