Reactor Fast and Slow Neutrons and Total Gamma Rays Distributions through Different Locally Prepared Concretes

BA study of the penetration of reactor fast, slow neutrons and total gamma rays through two new types of locally prepared concretes (basalt concrete, ρ=2.2 g/cm3 and magnetite concrete; ρ=3.9 g/cm3) has been carried out. Investigations have been performed in order to obtain the leakage spectra of fast, slow neutrons and gamma rays beams from cylindrical samples of these concrete shields using a collimated beam from ET-RR-1 reactor.
