This book focuses on the processing, materials design, characterisation, and properties of polymer composites and nanocomposites for use as electromagnetic radiation shielding materials and to enhance radiation shielding capacity in order to meet the safety requirements for use in medical X-ray imaging facilities. It presents an in-depth analysis of materials synthesis methods such as melt-mixing, ion-implantation, solution casting and electrospinning. In addition, it measures the X-ray attenuation behaviour of fabricated composites and nanocomposites in four major types of X-ray equipment, namely general radiography, mammography, X-ray absorption spectroscopy and X-ray fluorescence spectroscopy units. Given its scope, the book will benefit researchers, engineers, scientists and practitioners in the fields of medical imaging, diagnostic radiology and radiation therapy.
