The Navy shall ensure x-ray equipment used in Federal facilities meet the Federal Diagnostic x-ray equipment performance standards and be certified by the Food and Drug Administration (FDA).
This program includes PQS, structural shielding design, system evaluation, reporting procedures and dental radiological systems.
NAVMEDLOGCOM will notify commands and facilities receiving new and replacement medical radiological systems of the prospective installation date within 10 working das of equipment contract award.
COs shall ensure all systems are evaluated within 30 days of installation and after major repairs.
Ensure medical x-rays unites (fixed or mobile) ashore and on hospital ships are evaluated annually.
All other fixed x-ray units afloat require 24 month evaluation.
Dental fixed and portable x-ray units require 36 months evaluation.
Maintain all system evaluation reports for 3 years. Maintain structural radiation shielding for the lifetime of the facility.
Ensure a report of corrective actions is provided to the service command within 30 days of receipt of the x-ray survey report.
Prohibit use of radiological systems that fail to meet the basic radiation safety criteria.
Provide a summary report of each evaluated radiological system to the responsible CO within 30 working days from the completion of the survey.
The report of the NAS-NRC Committee on Biological Effects of Ionizing Radiation was issued in 1972.
One of the NAS-NRC Committee’s significant findings was that medical diagnostic radiology accounts for at least 90% of the total man-made radiation dose to which the U.S. population is exposed.
Ex. of examinations that should not be routinely performed unless such exception is made are: 1) TB screening by chest radiography, 2) chest x-raying for routine hospital admission of patients under age 20 or lateral chest x-rays for patients under age 40 unless a clinic indication of chest disease exists.
