Radiation Detection and Measurement Laboratory

The Radiation Detection and Measurement Laboratoryis a dual use space, utilized for both graduate and undergraduate teaching and research. This laboratory is equipped with essential instruments for the detection and measurement of alpha, beta, gamma, and neutron radiation. The space occupies approximately a 1,200 square feet area and is fitted with gas proportional counters, NaI scintillation spectrometers, silicon charged particle radiation detectors, and ³He neutron detectors. This lab flows in tandem with the Environmental Radionuclide Assay Laboratory, a low background counting research space designed to quantify radionuclide concentrations in environmental and other low activity samples. Specific additional equipment includes a low background 40% HPGe LabSOCS system, an HPGe ISOCS system and a multi sample liquid scintillation counter.
