Abstract
The experimental measurements of the transmitted and the reflected (albedo) components of the capture secondary gamma rays, arising from interaction of reactor neutrons with heat resistant concrete shields have been carried out. This new type of concrete has been prepared from Egyptian ilmenite-limonite ores and has a density 3.44 gm/cm3. The measurements were performed using a collimated beam of reactor neutrons emitted from one of the horizontal channels of the ET-RR-1 reactor.
A single stilbene crystal scintillator applying zero crossover technique for differentiation between gamma and neutron pulses has been utilized. The measured instrument spectra were transformed to energy spectra. From the measurements it is evident that the albedo capture gamma rays is very small in comparison with the total or the transmitted capture gamma rays.
