| 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 an 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. Technology Validation: The Purdue researchers identified the ratio between two plutonium isotopes ranging from 1:0 to 0:1 to an accuracy within 12% and under 10 keV energy resolution. Advantages - accurate - high-energy resolution and sensitivity - alpha and neutron radiation detection - 100% background gamma-beta rejection - rapid (<1 hr) Applications - spectroscopic detection of alpha and neutron radiation |
