Abstract

Information carrying impulses come from a probe with a radio-isotope source and secondary radiation detector. Impulse amplitude analyser comprises analysis-calculator channel for each element and two parallel mounted differential discriminaters for elements photoelectric peak in secondary radiation spectrum. Used for determining elements in rocks and minerals.
