Thallium-doped Sodium Iodide
Crystals are available in a wide range of standard sizes and configurations either as separate crystals or in complete assemblies. Maximum light transfer is achieved by employing a high efficiency reflector chosen to suit the particular application for which the crystal is required. Materials used are selected to ensure low background count.
