IMAGING POLICY AND PROCEDURE
Radiation protection for Radiology staff

Effective Date: September 1 2013 Approval: See Authorization
Supersedes Protocol: None Contact:

Reviewed


PURPOSE: To provide radiation protection procedures to OR staff, hospital employees, and
patients during radiology procedures.

POLICY:
A. All patients shall be protected to minimize exposure to radiation per exam and receive
only the amount necessary to get a diagnostic radiograph or Computed Tomography scan
(CT).
B. State rules require gonadal shielding whenever it is practical and would not compromise
the examination.
PROCEDURE:
A. Patient Radiation Safety for Diagnostic Radiographs and CT scans
1. Radiation field is to be collimated only large enough to include anatomic part to
be radiographed.
2. Where practical, the gonads on all patients are to be protected from scattered
radiation by the use of a gonads shield, except when the examination would be
compromised.
3. Exposure factors utilized must produce minimum amount of patient exposure and
still obtain a diagnostic radiograph.
B. Employee Radiation Safety for Diagnostic Radiography
1. The x-ray beam from the x-ray tube shall not be directed toward the entrances to
the room.
2. All room entrance doors must be closed during x-ray exposures.
3. Anyone holding or monitoring a patient during an exposure (including the mini
OEC) must wear a protective lead apron or vest and skirt. Thyroid lead shields
will be available to staff.
4. Radiology personnel should stand at least six feet from the patient during
portable examination exposures whenever possible.

5. Whenever possible, the portable x-ray machine is to be between the Radiology
Technologist and the patient.
6. Employee exposure monitoring will be determined by the Hospital Radiation
Health Physicist.
D. Inspection of Personal Radiation Protection Items
1. Quality control and maintenance procedures shall be performed on a regular
schedule according to the device manufacturer’s recommendations. If analysis
shows that the system test results fall outside the device manufacturer’s
recommended limits corrective action shall be taken prior to performing patient
examinations.
2. Personal radiation protection items in use will be tested by radiographic /
fluoroscopic inspection every year. If any personal radiation protection item in
use is discovered to not have been tested for more than two years, the medical
physicists responsible for oversight shall be notified by the manager or appointee.
Each employee and manager are also responsible for performing ongoing visual
inspections of personal radiation protection items and then bringing any item that
appears damaged to the attention of the managers who will, in turn, have
the medical physicists or appointee test the product.
E. Comprehensive quality assurance tests are performed on the radiographic equipment at
average annual intervals, with spot checks performed are requested, and after major repairs such
as x-ray tube replacement. These tests include measurements of image quality, radiation safety,
and overall performance of the equipment.
