Impact of micro/nano cadmium oxide on shielding properties of cement-ball clay matrix.

This study investigates the gamma radiation shielding properties of cement-ball clay matrix composites doped with micro- and nano-sized cadmium oxide (CdO) particles. The linear attenuation coefficient (LAC) was determined using a sodium iodide (NaI) detector and five radioactive point sources with energies ranging from 59.5 to 1408 keV.
