Canberra BE5030 thin windowed, 50% relative efficiency planar HPGe detector with DSA-2000 MCA. Allows broad energy measurements, especially effective for low-energy gamma (~20% absolute efficiency for 241Am 59.5 keV photons at close detector-source geometry) down to 20 keV. Useable for the quantification of 129I in specially prepared samples.
Canberra GC10021 large volume, 101% relative efficiency co-axial HPGe detector with DSA-2000 MCA. Good absolute efficiency for >1 MeV photons as well. Universally used for environmental and radiochemical samples.
A low-efficiency detector system for quick gamma assay at the L/ILW radiochemistry lab.
Liquid scintillation counters (LSC):
Perkin-Elmer TriCarb3180 TR/SL low activityliquid scintillation analyzer, routinely used for 3H, 14C, 36Cl, 90Sr, 99Tc measurements.
Perkin-Elmer Quantulus 1220 ultra-low level liquid scintillation spectrometer, routinely used for low level tritium measurements, experimentally used for other projects, such as 222Rn/226Ra measurements.
Oxford Oasis-MX alpha spectrometer with Tennelec and Ortec chambers equipped with 450 mm2 and 900 mm2 Routinely used for the measurement of air filters (larger chambers) and 239Pu, 241Am, etc. radiochemical samples (smaller chambers).
Canberra LB4200 low-background counter with 4 detectors. Routinely used for the measurement of evaporation residual of tap water samples, experimentally used for other projects, such as quick check before longer alpha spectrometryanalysis.
