Comparison of the Linear Attenuation Coefficient of Clay Samples As Potential Walling Material For Building Design by James Adeyemo Adegoke and Godwin Egbeyale (Pages 291-298)
Sale price: $5.00


This paper focused on two clay materials and studied their effectiveness as radiation shielding material. The samples were made into slabs and their linear attenuation coefficients were measured at different x-ray energies of 40kev, 60kev, 80kev, 100kev and 120 kev, at 10mA. One of the samples (Isan clay) was mixed with lead nitrate at various concentrations and the mixture was separated using filtration method. The second clay sample was obtained from an old lead battery dumped site inadvertently contaminated by lead. This was analyzed for linear attenuation in thi contaminated so as to possibly find a use for the soil after excavation as a way of remediation, Results obtained showed that as the thickness increases, the linear attenuation increases and which is in conformity with Lambert - Beer’s equation. It was observed that at thickness 4cm the radiation was unable to escape through the material (contaminated clay) while Isan clay stopped the radiation at 7cm thickness when energy was 40kev.
