associated equipment or radiation survey instruments under the personal
supervision of a radiographer trainer.
(36) Radiographer trainer--A radiographer who instructs
and supervises radiographer trainees during on-the-job training and
who meets the requirements of subsection (e)(3) of this section.
(37) Radiographic exposure device--Any instrument containing
a sealed source fastened or contained therein, in which the sealed
source or shielding thereof may be moved, or otherwise changed, from
a shielded to unshielded position for purposes of making a radiographic
exposure (e.g., camera).
(38) Radiographic operations--All activities associated
with the presence of x-ray machines or radioactive sources in a radiographic
exposure device during the use of the machine or device or transport
(except when being transported by a common or contract transport).
Radiographic operations include surveys to confirm the adequacy of
boundaries, setting up equipment, and any activity inside restricted
area boundaries.
(39) Radiographic personnel--Any radiographer, radiographer
trainer, or radiographer trainee.
(40) Residential location--Any area where structures
are located in which people lodge or live, and the grounds on which
these structures are located including, but not limited to, houses,
apartments, condominiums, and garages.
(41) S-tube--A tube through which the radioactive source
travels when inside a radiographic exposure device.
(42) Shielded position--The location within the radiographic
exposure device or source changer where the sealed source is secured
and restricted from movement.
(43) Shielded-room radiography--Industrial radiography
conducted in a room shielded so radiation levels at every location
on the exterior meet the limitations specified in §289.202(n)
of this title or §289.231(o) of this title, as applicable. A
shielded room is also known as a bay or bunker.
(44) Source assembly (pigtail)--An assembly that consists
of the sealed source and a connector that attaches the source to the
control cable. The source assembly may also include a ball stop used
to secure the source in the shielded position.
(45) Source changer--A device designed and used to
replace sealed sources in radiographic exposure devices, including
those used to transport and store sealed sources.
(46) Storage area--Any location, facility, or vehicle
that is used to store and secure a radiation machine, radiographic
exposure device, a storage container, or a sealed source when it is
not used for radiographic operations. Storage areas are locked or

or unauthorized removal of the machine, device, container, or source.
(47) Storage container--A device in which the sealed
source is secured and stored.
(48) Storage facility--A structure designed to house

imaging devices are exempt from the requirements in this section if
the exposure rate 18 inches from the source of radiation to any individual
does not exceed 2 millirem per hour (mrem/hr) (0.02 millisievert per
hour (mSv/hr)). Devices with exposure rates that exceed the 2 mrem/hr
(0.02 mSv/hr) level shall meet the applicable requirements of this
