Abstract The paper is devoted to determination of boron and nitrogen in metallic materials by nuclear track techniques for the case of high background in radiograms. The method is based on the detection of the 10B(n,α)7Li and 14N(n,p)14C reaction products with plastic track detectors exposed to a neutron flux in a close contact with the samples analyzed. When determining boron, high background can arise due to fast neutron interactions with hydrogen existing in the detector material and with matrix elements of the sample. In the case of nitrogen determination, high background is usually associated with a presence of boron in metals and alloys, alpha tracks of which strongly interfere with proton tracks from the 14N(n,p)14C reaction. The feasibility for measurement of micro-concentrations of boron as well as nitrogen determination in the presence of boron has been studied.
