Abstract |
|
|
| The usage of radioactive sources has grown recently due to the advancement of nuclear science and technology in a variety of disciplines, including nuclear research facilities, nuclear power plants, space exploration, and medical care. This study is aimed at investigating the gamma radiation shielding capability of fabricated concrete doped with coconut shell ash at different mixing ratios (x=5, 10, 15, 20, 25, 30, 35, 40) wt%, and X-ray Fluorescence (XRF) technique was used to determine the elemental composition of the composites, WinXcom software were used to generate the attenuation coefficients. The result shows that the maximum (minimum) mass attenuation coefficient values were obtained at photon energies of 0.02 (15.00) MeV for all samples (A1-A8), which shows a reduction in MAC values as energy increases for the entire sample. The trend of the linear attenuation coefficient appears to be similar to that of the mass attenuation coefficient. The half-value thickness and mean free path appear to be similar and generally increase with photon energy for all the samples. These indicate that penetration is directly proportional to the energy of photons; hence, for higher energy photons, a thicker absorbing material is required. The fabricated concrete doped with coconut shell ash shows better attenuation capability than ordinary concrete and slightly below the shielding capability of lead. |
