Leticia S. Pibida, Ryan P. Fitzgerald, Michael P. Unterweger, Michelle M. Hammond, Daniel B. Golas
Half-life measurements of 82Sr were performed at the National Institute of Standards and Technology (NIST) using gamma-ray spectrometry and a 4 pressurized ionization chamber. The 82Sr half-life was determined to be 25.36 ± 0.03 days (k=1) using the

Performance of CdTe, HPGe and NaI(Tl) Detectors for Radioactivity Measurements

A Perez-Andujar, Leticia Pibida
The characteristics and performances of the NIST High Purity Germanium (HPGe), Sodium Iodide (NaI(Tl)) and Cadmium Telluride (CdTe) gamma-ray detectors were studied. The efficiencies, the minimum detectable activities and the energy resolutions each were
