Introduction and General Clarifications
Introduction
The task group:
"Protocols on The Radiation Safety
Survey of Diagnostic Radiological Equipment" was formed
by the Diagnostic X-ray Imaging Committee to provide a
unified approach to radiation
surveys of x-ray imaging
equipment conducted by radiologic physicists. Stationary
and mobile radiographic, fluoroscopic, dental x-ray, and
mammographic equipment are
covered.
Due to
its
specialized requirements computed

The protocols described
are intended to verify
compliance with the radiation safety regulations outlined
in the Code of Federal Regulations and the majority of
state agencies.
State regulations

Therefore, it is recommended
that the

regulations be reviewed prior
to conducting surveys.

for use by state-employed inspectors which may be useful
in certain situations.
General Clarifications
"Good Radiological Practices" set forth by the Joint
Commission on Accreditation of Hospitals (JCAH) require
that patients and personnel are protected from radiation,
electrical, and mechanical hazards associated with x-ray
equipment and that quality images
