Improvements to alpha-particle spectrometry techniques

Chemically selective polymer substrate based direct isotope dilution alpha spectrometry of Pu

“…A new cloud point extraction procedure coupled to inductively coupled plasma mass spectrometry and alpha spectrometry has been found to be effective for the plutonium quantification [9]. In addition to separation/preconcentration methods, the improvements to data analyses in alpha-particle spectrometry have been also attempted [10].…”

An alpha–gamma coincidence spectrometer based on the photon–electron rejecting alpha liquid scintillation (PERALS®) system

“…Another advantage of the coincidence counting method is the ability to directly determine the absolute disintegration rate of the source from the counting data without prior calibration to measure efficiencies of the detectors. This technique has been known [30] and used in a variety of applications including safeguards measurements [31,32], production of primary standards [33,34], or improving nuclear decay data schemes [35][36][37]. In practical applications, employing either beta-gamma or gammagamma coincidences, there are numerous corrections that are required depending upon the desired accuracy.…”
