1.0 INTRODUCTION
The XR150 produces high levels of radiation and must be operated by qualified personnel who
have read the Warning and Operations section of the manual before operating the device.
The XR150 is a small, lightweight x-ray generator that operates on its own removable battery pack. The
XR150 is a pulsed x-ray device that produces x-ray pulses of very short duration (30 nanoseconds). It
produces a low dose rate comparable to a 0.1 ma constant potential machine. The energy produced by
the XR150 is up to 150KVP, which makes it possible to radiograph up to one (1/2) inch (1 cm) of steel.
XR150 standard accessories are two keys, two battery packs, and one battery charger. Remote cable,
carrying case, and film developing equipment are also common accessories.
2.0 WARNINGS
The XR150 is a pulsed X-ray generator that emits hazardous ionizing radiation when pulsing. The
XR150 should only be operated by authorized personnel who are properly trained to safely operate the
generator. The XR150 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 XR150. 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 XR150 is used
within federal and state guidelines.
All operators and users of the XR150 x-ray machine must wear a personal radiation monitoring device,
such as a TLD (thermoluminescent dosimeter), film badge, and/or a pocket dosimeter consistent with
the appropriate federal, territorial or provincial standards (note: an electronic dosimeter will not
detect the XR150 radiation pulses).
Due to the short pulse width of the XR150, 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 XR150 does not produce constant
radiation. The XR150 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 XR150 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.
DUTY CYCLE WARNING. The XR150 is a light duty machine that is not made to pulse
continuously. The maximum duty cycle for the XR150 is 100 counts every four minutes (1500 counts
(4500 pulses) per hour). Exceeding the duty cycle will shorten the life of the tube and head.
