I. Space Requirements:
a. The operator shall be
allotted not less than 7.5 square feet (0.70m2) of
unobstructed floor space in the booth.
b. The operator's booth may be any geometric
configuration with no dimension of less than 2 feet (0.61 m).
c. The space shall be allotted excluding any
encumbrance by the x-ray control panel, such as overhang, cables, or other
similar encroachments.
d. The booth
shall be located or constructed such that unattenuated direct scatter radiation
originating from the examination table or at the wall cassette holder will not
reach the operator's position in the booth.
II. Structural Requirements:
a. The booth walls shall be permanently fixed
barriers of at least 7 feet (2.1 m) high.
b. When a door or movable panel is used as an
integral part of the booth structure, it must have an interlock which will
prevent an exposure when the door or panel is not closed.
c. Shielding shall be provided to meet the
requirements of Subchapter 4 of these regulations.
III. X-Ray Exposure Control Placement:
a. The x-ray exposure control for the system
shall be fixed within the booth and:
b. Shall be at least 40 inches (1.0 m) from
any open edge of the booth wall which is nearest to the examining
table.
c. Shall allow the operator
to use the majority of the available viewing windows.
IV. Viewing System Requirements:
a. Each booth shall have at least one viewing
device which will:
i. Be so placed that the
operator can view the patient during any exposure, and
ii. Be so placed that the operator can have
full view of any occupant of the room and should be so placed that the operator
can view any entry into the room. If any door which allows access to the room
cannot be seen from the booth, then outside that door there shall be an "x-ray
on" warning sign that will be lighted anytime the rotor of the x-ray tube is
activated. Alternatively, an interlock must be present such that exposures are
prevented unless the door is closed.
b. When the viewing system is a window, the
following requirements also apply:
i. It
shall have a viewing area of at least 1 square foot (0.093
m2).
ii.
Regardless of size or shape, at least 1 square foot of the window area must be
centered no less than 2 feet (0.61 m) from the open edge of the booth and no
less than 5 feet (1.52 m) from the floor.
iii. The window shall have at least the same
lead equivalence as that required in the booth's wall in which it is
mounted.
c. When the
viewing system is by mirrors, the mirror(s) shall be so located as to
accomplish the general requirements of Appendix B.IV(A).
d. When the viewing system is by electronic
means:
i. The camera shall be so located as to
accomplish the general requirements of Appendix B.IV(A), and
