The LAD-64 and LAD-66 detector assemblies are intended for the measurement of volumetric activity of gamma radionuclides in liquids, typically in process waters of nuclear facilities. The detector assembly is composed of a 2.5” (LAD-64) or 1” (LAD-66) NaI(Tl) scintillation detector, shielded measurement chamber, LED check source. The detector is usually connected to a radiation processing unit with a multi-channel analyser
