1.0 INTRODUCTION
The XR200 produces high levels of radiation and must be operated by qualified personnel who must read the Warning and Operations section of the manual before operating the device.
The XR200 is a 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
(60 nanoseconds). It produces a relatively low dose rate comparable to a 1 mA constant potential machine. The energy produced by the XR200 is up to 150 KVP, which makes it possible to penetrate up to .4 inches (1 cm) of steel.
The XR200 comes with 2 battery packs, 2 keys, 1 battery charger, 1 tripod adapter, 1 remote operating cable, and a carrying case.
2.0 WARNINGS
2.1 The XR200 is an industrial type x-ray generator that produces hazardous radiation when energized.
2.2 It is unlawful to use this equipment to intentionally expose humans or to use it for medical radiography.
2.3 The XR200 is subject to state regulation and registration. Contact your state board of health before operating this equipment.
2.4 The operator must be properly trained to safely operate the XR200 X-ray unit.
2.5 Unauthorized personnel should not have access to the XR200.
2.6 Develop and closely follow a safe operating system for using the XR200.
2.6.1 The safe operating system must ensure that no one is exposed to radiation above the permissible limits as established by your local regulatory agency.
2.6.2 The safe operating system must ensure the XR200 is used within federal and state guidelines.
2.7 All operators and users of the XR200 must wear a personal radiation monitoring device, such as a TLD (thermoluminescent dosimeter), film badge, or a pocket dosimeter, consistent with the appropriate federal, state, territorial, or provincial standards (note: an electronic dosimeter will not detect the XR200 radiation pulses).
2.7.1 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
- 2 -
from the x-ray source. Survey meters should be of the ionization gage type and should
be used in the integration mode.
2.7.2 Survey 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.
2.8 The XR200 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.
3.0 PHYSICAL DESCRIPTION
3.1 HIGH VOLTAGE PULSER/TUBEHEAD. The front half of the XR200 consists of a
4-inch diameter canister that is rounded at its end.
3.1.1 The canister contains the high voltage generator and the x-ray tube.
3.1.2 A radiation-warning label is located on each side of the canister.
3.1.3 A beam angle label located on the front of the canister indicates the direction and angle the x-ray beam leaves the XR200.
3.2 BASE. The base of the XR200 accomodates the threaded tripod mount. Using the tripod mount release button, the XR200 can be quickly and easily mounted on any standard photographic tripod.
3.2.1 A label identifying the model, manufacturer, and serial number is located on the bottom of the XR200 base.

When using Polaroid
positive film: If the radiograph is too dark, the film is underdeveloped. If the radiograph is too light or washed out, the film is overexposed.
4.4 DUTY CYCLE WARNING. Up to 200 pulses may be used without resting the
XR200. After every 200 pulses, the operator should allow a rest period of 4 minutes.
The XR200 is a light duty machine. It is not made to pulse continuously.
5.0 SOFTWARE
5.1 The software program that controls the microcontroller can be identified by turning the key switch on while both push button switches below the LCD are depressed. The LCD displays the software version “40”. When the push button switches are released, the LCD will display “00” and the XR200 is ready for operation. If the operator continues to hold both push button switches down after “40” is displayed the LCD will display the total number of pulses on the unit. The number displayed in the right column of the LCD represents 10,000 pulses. The number in the left column represents 100,000 pulses. A reading of “07” indicates are between 60,000 and 70,000 pulses on the XR200.
5.2 The software program in the control module is capable of indicating 2 conditions:
5.2.1 The first condition is detected if there are more than .33 seconds between two consecutive pulses.
5.2.1.1 The XR200 continues the current pulse train to “00”.
- 6 -
5.2.1.2 After the XR200 stops pulsing, the LCD will go back to the original pulse setting, but the left and right digits will blink alternately.
5.2.1.3 The condition indicates a low battery.
5.2.1.4 The XR200 will be inoperable until the key switch is turned off and on, or the battery is replaced.
5.2.2 The second condition is detected if there is more than 1 second between two consecutive pulses.
5.2.2.1 The XR200 stops pulsing immediately and the LCD displays “00”.
5.2.2.2 This function prevents XR200 from pulsing continuously if there is a failure in detecting circuitry.
5.2.2.3 This condition may indicate a low battery, electrical noise, or failure in detecting circuitry.
5.2.2.4 The operator may need to replace the battery pack, turn key switch off and on, or send the XR200 back for repair.
6.0 MAINTENANCE
6.1 X-RAY DOSE MEASUREMENT. Using a dosimeter, the average X-ray dose for each new tube can be established.
6.1.1 With the dosimeter located 1 foot from the front of the case and in line with the center of the beam angle label, the reading for 10 counts should be 31 mR+/- 5 mR.
6.1.2 Figure 2 on page 13 illustrates the X-ray dose and maximum allowable
radiation leakage levels for each X-ray unit.
6.1.3 The leakage and dose of the tube should be measured every 30,000 pulses or
