Abstract
Abstract A shielding apparatus for use in conjunction with an X-ray generator is disclosed. The apparatus comprises a shielding cone extending from the X-ray generator toward the object to be X-rayed, said cone comprising an upper cone portion detachably connected to the X-ray generator, a lower cone portion forming the base of the cone and a plurality of panels detachably connected to and extending between the upper and lower cone support portions. Additional shielding components are provided about the X-ray generator and secured to the shielded cone to further reduce the emission of stray X-rays.
