APPROXIMATE SHIELDING CALCULATIONS

Technical Report ·
OSTI ID:4843896
Equations and nomograms are given for finding approximate gamma shielding requirements. The actual source is replaced by a point source, and the dose rate from the shielded point source is found as a function of the source strength, gamma energy, source-receptor distance, shield thickness, and shield attenuation factor. Attenuation factors are presented for ordinary concrete, magnetite concrete, lead, iron, water, and high-density glass. The method may be used for sources with several gamma energies. (T.F.H.)
