Since the contribution of the scattered flux to the total measured flux in experiments at the Tower Shielding Facility must be known for a variety of conditions, much of the work of the Shielding Analysis Group has been directed toward calculations of neutron ground and air scattering. These calculations are being compared with similar calculations at other installations. In addition, a calculation of the fast-neutron leakage from the Bulk Shielding Reactor was performed, and agreement with leakage flux measurements made with the recoil proton spectrometer indicates that the reactor power density determinations are correct. A calculation by the Monte Carlo method of the number and energy of slant incident photons that penetrate or are reflected from a finite thick slab of infinite extent was also made.
