Neutron shielding is done to protect workers from excessive radiation and to keep a low neutron background for research in neutron counting. To meet health standards the total neutron flux allowable is 150 n/cm/sec per eight hours, or 50 n/cm/sec per twenty-four hours. Literature values for the absorption coefficients of paraffin and water are considered, and some experimental data is presented which approximately confirm them. A description of barriers at Mound Laboratory is given. Plans for future work on slowing-down of fast nautrons and capture of slow neutrons are included
