NAC459.578. Fluoroscopic X-ray systems: Control of scattered radiation.

     1. Fluoroscopic table designs when combined with procedures utilized, must be such that no unprotected part of any staff or ancillary person’s body will be exposed to unattenuated scattered radiation which originates from under the table. The attenuation required must be not less than 0.25 mm lead equivalent.

     2. Equipment configuration, when combined with procedures, must be such that no portion of any staff or ancillary person’s body, except the extremities, are exposed to the unattenuated scatter radiation emanating from above the tabletop unless the person:

     (a) Is at least 120 cm from the center of the useful beam; or

     (b) The radiation has passed through not less than 0.25 mm lead equivalent material, for example, drapes, Bucky-slot cover, sliding or folding panel or self-supporting curtains, in addition to any lead equivalency provided by the protective apron referred to in subsection 1 of NAC 459.554.

     3. Upon application to the Division with adequate justification, exceptions to subsection 2 may be made in some special procedures where a sterile field will not permit the use of the normal protective barriers or where the protective barriers would interfere with the procedures.
