Mich. Admin. Code R. 333.5365 - Enclosures
Rule 365.
(1)
The degree of protection required for an enclosure shall be determined by the
workload, use and occupancy factors, and the tube potential, tube current,
mechanical movement, and distance, and shall be subject to design approval by
the department.
(2) In a
radiographic room, wall and floor areas exposed to the useful beam plus an area
extending at least 30 centimeters (1 foot) beyond shall be provided with a
primary protective barrier where necessary as determined by workload, use and
occupancy factors, and distance.
(3) Secondary protective barriers shall be
provided in the radiographic room ceiling and in those walls not requiring
primary barriers. Common building materials often fulfill this
requirement.
(4) A fixed barrier of
1.6 millimeters (1/16 inch) lead equivalence, such as a shielded wall partition
or immobilized portable shield, is recommended for operator protection. When
this protection is provided, the operator shall be able to see and communicate
with the patient from a shielded position.
