Appendix B - DESIGN REQUIREMENTS FOR AN OPERATOR'S BOOTH

1. Space Requirements:

(a) The operator shall be allotted not less than 0.70 m² (7.5 square feet) of unobstructed floor space in the booth;

(b) The operator's booth may be any geometric configuration with no dimension of less than 0.6 m (2 feet);

(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 on the examination table or at the wall-mounted image receptor will not reach the operator's position in the booth.

2. Structural Requirements:

(a) The booth walls shall be permanently fixed barriers of at least 2 m (7 feet) 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 Part D of these regulations.

3. Radiation Exposure Control Placement:

The radiation exposure control for the system shall be fixed within the booth and:

(a) Shall be at least 1.0 m (40 inches) from any point subject to direct scatter, leakage or primary beam radiation;

(b) Shall allow the operator to use the majority of the available viewing windows.

4. Viewing System Requirements:

(a) Each booth shall have at least one viewing device which will:

(1) Be so placed that the operator can view the patient during any exposure; and

(2) 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 shall 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:

(1) The window shall have a viewing area of at least 0.09 m² (1 square foot);

(2) Regardless of size or shape, at least 0.09 m² (1 square foot) of the window area must be centered no less than 0.6 m (2 feet) from the open edge of the booth and no less than 1.5 m (5.0 feet) from the floor;

(3) 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 B4.(a).

(d) When the viewing system is by electronic means:

(1) The camera shall be so located as to accomplish the general requirements of Appendix B4.(a); and

(2) There shall be an alternate viewing system as a backup for the primary system.
