Vs. Nakhabtsev et Kv. Bukin, A PORTABLE X-RAY-SPECTRUM GAUGE FOR AN ANALYZER OF ELEMENT COMPOSITION, Instruments and experimental techniques, 41(3), 1998, pp. 401-405
A portable X-ray spectrum gauge is described. This gauge allows the de
signing of a portable analytical instrument for measuring the content
of chemical elements with atomic numbers exceeding 20 (Ca) directly at
the location of the object under study. The concentrations of many el
ements with detection thresholds of 10(-3)-10(-2)% can be determined w
ith this instrument.
