The neutron induced microscopic radiography is a suitable method to detect boron content and distribution in metallic materials. For the research reactor KRR-2, the optimum thermal neutron fluence for various amount of boron content, the background effect due to fast neutron and -ray to the minimum detection limit of boron content, as well as the optimum-etching condition of the solid state nuclear track detector were determined.
