1.0 INTRODUCTION
The XRS3 is a small, lightweight X-ray generator that operates on its own removable battery pack. The XRS3 is a
pulsed X-ray device that produces X-ray pulses of very short duration (25 nanoseconds). It produces a relatively
low dose rate comparable to a 0.25 ma constant potential machine. The energy produced by the XRS3 is up to
270kVp, which makes it possible to radiograph up to one (1) inch (2.54 cm) of steel.
XRS3 standard accessories are two keys, two battery packs, and one battery charger. Remote cable and carrying
case are also common accessories.
2.0 WARNINGS
The XRS3 is a pulsed X-ray generator that emits hazardous ionizing radiation when pulsing. The XRS3 should only
be
operated by authorized personnel who are properly trained to safely operate the generator. The XRS3 must
be registered with proper authorities prior to use and should not be used to intentionally expose humans.
Develop and closely follow a safe operating system for using the XRS3. The safe operating system must ensure that
no one is exposed to radiation above the permissible limits which are 2 mR (0.02 mSv) per hour for a member of
the public.
The safe operating system must ensure the XRS3 is used within federal and state guidelines.
All operators and users of the XRS3 X-ray machine must wear a personal radiation monitoring device, such as
a TLD (thermoluminescent dosimeter), lm badge, and/or a pocket dosimeter
consistent with the appropriate
federal, territorial or provincial standards (note: an electronic dosimeter will not detect the XRS3 radiation pulses).
Due to the short pulse width of the XRS3, survey meters of the Geiger-Mueller and scintillator type do not accurately
detect the radiation emitted from the x-ray source.
Survey meters should be of the ionization type and should be used in the integration mode . Survey meters must not
be used in the rate mode because the XRS3 does not produce constant radiation. The XRS3 produces very high
rates of radiation for very short periods of time resulting in either unrealistically high readings or no readings for
a survey meter in rate mode.
The XRS3 has no explosion proof rating and should not be used in an explosive atmosphere. The Spark Gap
is vented to the air and could be a source of ignition.
STORAGE & USE: Store and use the XRS3 in upright position. Upside down storage or use may cause premature
failure including no output dose.
The XRS3 produces high levels of radiation and must be operated by quali ed personnel who have read the
WARNINGS and OPERATING INSTRUCTIONS sections of the manual before operating the device.
DUTY CYCLE WARNING. The XRS3 is a light duty machine that is not made to pulse continuously. The
maximum duty cycle for the XRS3 is 200 pulses every four minutes (3000 pulses per hour). Exceeding the
duty cycle will shorten the life of the tube and head. In temperatures above 90 °F (32.22 °C) or continual
use, rest 30 seconds after every 50 pulses and 4 minutes after every 200 pulses.
