Comprehensive shielding behaviors of chambersite deposit in China for neutron and gamma ray were systematically analyzed for the first time. Monte-Carlo method simulation technique, American Evaluated Nuclear Data File (ENDF/B-VIII.0), XCOM program and Phy-X/PSD program were used to perform the analysis. Transmission against different neutron resources and cross section for neutrons, mass attenuation coefficient, half value thickness, effective atomic number and electron density for narrow beam gamma ray at 0.001–100000 MeV, and equivalent atomic number, G-P Fitting Parameters, exposure buildup factors and energy absorption buildup factors against wide beam gamma ray for penetration depths up to 40mfp at 0.015–15 MeV were obtained. Shielding performance of chambersite deposit is excellent for high energy and low energy neutrons because of Mn and B respectively, and better than SWX …
