Abstract

Researchers at Purdue University have developed a new spectroscopic method for detecting trace amounts of alpha-emitting radionuclides. Traditionally, detecting closely-spaced energetic alpha radiation-emitting isotopes at trace concentrations needing mass spectrometry has taken weeks. On the other hand, the Purdue hybrid technology rapidly and spectroscopically detects alpha radiation with ~100% sensitivity, less than 10 keV resolution, and accuracy within 5% when evaluated against standards. This technology also maintains its sensitivity to weak alpha radiation in an intense field of gamma-beta radiation; the same apparatus also can be deployed for high-fidelity neutron spectroscopy.
