Radiation transmission of heavyweight and normal-weight concretes containing colemanite for 6Â MV and 18Â MV X-rays using linear accelerator

Accurate measurements have been made to determine radiation transmission of concretes produced with barite, colemanite and normal aggregate by using beam transmission method for 6 and 18 MV X-rays with a linear accelerator (LINAC). Linear attenuation coefficients of thirteen heavy- and four normal-weight concretes were calculated. It was determined that linear attenuation coefficient (μ, cm−1) decreased with colemanite concentration and increased with barite concentration in both types of the concretes.
