Abstract
In this study, dependence of gamma-ray absorption coefficient on the size of Pb particle size ranging from 200µm up to 2.5mm, using different weights of each particle size. The results show that gamma-ray attenuation coefficient is inversely proportional with the size of Pb particle size due to the reduction of the spaces between the lead particles.
Highlights
Radiation shielding commonly used to protect medical patients and workers from exposure to direct and secondary radiation during diagnostic imaging in hospitals, clinics and dental offices
All radioactive materials in the laboratory or place of work should be surrounded by sufficiently thick shielding material such that the radiation in neighboring work areas is kept at minimum permissible levels
Radiation shielding aprons and coverings have been manufactured from lead powder-loaded polymer or elastomeric sheets
Summary
Radiation shielding commonly used to protect medical patients and workers from exposure to direct and secondary radiation during diagnostic imaging in hospitals, clinics and dental offices. All radioactive materials in the laboratory or place of work should be surrounded by sufficiently thick shielding material such that the radiation in neighboring work areas is kept at minimum permissible levels. This quantity of shielding is determined by the material chosen. Lead is often used because of its high atomic number and density. As well, it is soft and malleable and cast into various forms.
