Determination of microquantities of Be in samples using α-sensitive track etch detectors

Solid-state track detectors in radiometry, isotope analysis, and radiography

“…When determining the content of Be in samples using 4.6-9-MeV γ-quanta, impurities of B and Li were determined by sample irradiation with thermal neutrons [19]. In addition, to reduce the background from Li impurities, the samples were heated prior to irradiation to evaporate lithium.…”
