Although gypsum is one of synthetic building materials, nowadays it is used as interior coating of walls and ceilings of buildings. Thus, measurement of its radiation shielding properties is vital. The gamma attenuation coefficients of gypsum concretes, produced using different rates of boron, have been measured at gamma energies of 511, 835 and 1275 keV. The measured results have been compared with the results of calculation, which has been done using XCOM computer code. The obtained results have also been compared with the normal type of gypsum concrete, in order to see the effect of boron on the radiation shielding properties.
