E.
INTENTIONAL INDUSTRIAL X-RAY
DEVICES
i.
Industrial X-Ray Devices.
Industrial X-ray devices are used for
radiography, for example, to take pictures
of the inside of an object as in an X-ray of a
pipe weld or to measure the thickness of
material. ANSI standard N43.3 defines five
classes of industrial X-ray installations:
cabinet, exempt shielded, shielded,
unattended, and open.
(Add facility-specific examples.)
ii.
Cabinet X-ray Installation.
A cabinet X-ray installation is similar in
principle to the analytical enclosed beam
system. The X-ray tube is installed in an
enclosure (cabinet) that contains the object
being irradiated, provides shielding, and
excludes individuals from its interior during
X-ray generation. A common example is
the X-ray device used to inspect carry-on
baggage at airline terminals. Certified
cabinet X-ray systems comply with the
regulations of 21 CFR 1020.40.
