The XR200 is a small, lightweight x-ray generator that operates on its own removable battery pack. The XR200 is
a pulsed X-ray device that produces X-ray pulses of very short duration (50 nanoseconds). It produces a low dose
rate comparable to a 0.5 ma constant potential machine. The energy produced by the XR200 is up to 150KVP,
which makes it possible to radiograph up to one (1/2) inch (1.27 cm) of steel.
XR200 standard accessories are two keys, two battery packs, and one battery charger. Remote cable, carrying
case, are also common accessories.
The XR200 is a pulsed X-ray generator that emits hazardous ionizing radiation when pulsing. The XR200 should
only be by who are properly trained to safely operate the generator. The XR200
must be with proper authorities prior to use and should be used to intentionally expose humans.
Develop and closely follow a safe operating system for using the XR200. 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 XR200 is used within federal and state guidelines.
All operators and users of the XR200 X-ray machine must wear a personal radiation monitoring device, such as
a TLD (thermoluminescent dosimeter), lm badge, and/or a pocket dosimeter
(note: an electronic dosimeter will not detect the XR200 radiation
pulses).
Due to the short pulse width of the XR200, 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 modeSurvey meters must not
be used in the rate mode because the XR200 does not produce constant radiation. The XR200 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.
Upside down storage or use may cause
premature failure including no output dose.
The XR200 is a light duty machine that is not made to pulse continuously. The maximum
duty cycle for the XR200 is 200 pulses every four minutes (3000 pulses per hour). Exceeding the duty cycle will
shorten the life of the tube and head.
