Preparation of polymers suitable for radiation shielding and studying its properties
(polyester composite with heavy metals salts)(4JjSj jluit i—iSlj2a)
M.H. Kharita, Z. Al-Ajji, S. Yousef
Abstract
Four composites were prepared in this work, based on polyester and heavy metals oxides and salts. The attenuation properties, as well as mechanical properties were studied, and the chemical stability was evaluated.
It has been shown, that these composites can be used in radiation shielding for X-rays successfully, and the exact composition of these composites can be optimized according to the radiation energy to prepare the lightest possible shield.
KeywordsPolymers, Radiation shielding, X-ray, Polyester
