§ 221.42a. Control of scattered radiation.

 (a)  Fluoroscopic table designs when combined with normal operating procedures shall be of a type so no unprotected part of the staff or an ancillary individual’s whole body is exposed to unattenuated scattered radiation which originates from under the table. The attenuation required may be not less than .25 millimeter lead equivalent.

 (b)  Equipment configuration when combined with normal operating procedures shall be of a type so that no portion of the staff or an ancillary individual’s whole body, except the extremities, is exposed to the unattenuated scattered radiation emanating from above the table top unless one of the following criteria is met:

   (1)  The individual is at least 120 centimeters from the center of the useful beam.

   (2)  The radiation has passed through at least .25 millimeter of lead equivalent material—for example, drapes, bucky-slot cover (film-tray cover panel), sliding or folding panel or self supporting curtains—in addition to lead equivalency provided by the protective apron referred to in §  221.11(e) (relating to registrant responsibilities).


   The provisions of this §  221.42a issued under sections 301 and 302 of the Radiation Protection Act (35 P. S. § §  7110.301 and 7110.302); and section 1920-A of The Administrative Code of 1929 (71 P. S. §  510-20).
