PORTABLE X-RAY FLUORESCENCE DEVICE WITH FLEXIBLE BACKSCATTER SHIELD

摘要

A radiation shield and method for reducing ambient radiation levels at a distance from a surface irradiated by penetrating radiation emanating from an instrument. The shield attaches to an end of the instrument abutting an irradiated surface and has a platen of attenuating material disposed within a plane substantially transverse to the propagation direction of penetrating radiation and substantially adjacent to the irradiated surface.
