Popis: | It is suggested that absorbing screens with 10B be used to maintain constant sensitivity under prolonged irradiation of fission chambers with natural uranium. The transmission factor Tα(E) of boron screens with various thicknesses (δ = 0.1–2 ge/cm2) for a wide neutron energy range and attenuation of a spectrum of the type ϕe/E are estimated. The group and average group constants of the transmission factor of boron are calculated for neutron fluxes in 25 energy groups of the neutron cross sections library. |
