摘要:
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 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.
