Answer to Question #6186 Submitted to "Ask the Experts"Category: Medical and Dental Equipment/Shielding — Shielding The following question was answered by an expert in the appropriate field: Q
I am a fellow working in the catheterization lab. Where is the best
place to put the front shield we used, to have the best protection from
radiation? Should it be placed on top of the patient, in between the
camera and the operator, or should it be placed lower, in between the
table and the operator?
A
Since you did not describe how this shield is mounted, I will give
you the basic shield locations in a typical cardiac catheterization
lab. A clear lead-impregnated plastic or glass shield is usually
mounted on the ceiling and pulls down in front of the operator's head
and neck area. A set of lead drapes is usually mounted on the table,
hanging down between the x-ray tube and the physician. A mobile shield,
which typically has clear lead-impregnated plastic or glass, can be
rolled and positioned between the x-ray unit and the physician. There
is also, of course, a lead apron for each person in the room.
If you have a type of shield that can be positioned in a variety of
places, and it is the only shield you have except for your lead apron,
I recommend that it is placed between the image intensifier/patient
area and your head and neck area. Since the remainder of your torso and
critical organs are covered by a lead apron, this will provide
protection for your head area, including the lens of the eyes.
