Cutting Edge


ITG has a variety of radioanalytical counting equipment including alpha, beta, and gamma counters. Most of the work with radiopharmaceuticals is done using NaI well crystals which we have coupled to ultichannel analyzers and sample changers. We also have several Ge crystals for high resolution gamma spectroscopy plus liquid scintillation capabilities to work with beta-emitting radionuclides.
