ABSTRACT:
A radiation shield and method for reducing ambient radiation levels at a distance from a surface irradiated by penetrating radiation emanating from an instrument substantially along a propagation axis. The shield attaches to an end of the instrument proximate to an irradiated surface and has a surface of attenuating material disposed with a component extending outward from the propagation axis of penetrating radiation and substantially adjacent to the irradiated surface.
