Abstract
A flexible, lightweight radiation absorbing sheet or shield includes heavy metal particles in one layer and mid-atomic number particles in another layer, the layer that will be adjacent to the patient. The shield is particularly intended for protection of the wearer and others from radiation emanating from a therapeutic source positioned within the patient's body. With the disclosed multi-layer shield construction, backscattered radiation off the heavy metal particle layer, affecting the patient's adjacent tissue, is minimized.
