On the basis of flight-time difference the direct and scattered neutrons as well as gammas produced in the target head and samples were separated. Using this method the attenuation of primary neutrons and gammas originating from the target head has been studied in addition to the measurements on the thickness dependence of the secondary gamma yield from extended samples of Al, Fe, Pb, paraffin and reinforced concrete. Results indicate a geometry dependence of the removal cross sections. The removal cross section of brick, gravel, sand, river sand, reinforced concrete and water has also been measured by activation threshold detector technique.
