Abstract
Described herein are radiation detection systems and methods that provide improved discrimination between different types of radioactive events. The use of multiple discriminator settings based on pulse curve shape, rather than a single setting, is surprisingly found to improve discrimination between alpha and beta events. Results demonstrate significantly lowered % spill with minimal loss of efficiency due to the enhanced discrimination. These systems and methods are particularly important in the detection of extremely low-level alpha and beta events, and in the identification and quantification of isotopes with difficult-to-distinguish pulse shapes.
