Quantitative analysis of nitrogen in various materials by track radiography

Abstract

The dependence of autoradiographic sensitivity of the CR-39 detector to 0.584 MeV protons produced by a thermal neutron-induced ¹⁴N(n, p)¹⁴C reaction in a thick target on the thickness of a removed layer of a detector is found theoretically and experimentally. The feasibility for nitrogen in various materials to be analysed quantitatively by track autoradiography is estimated.
