Niton XL2 Analyzer User's Guide
Avoid holding the front of the analyzer when the x-ray tube is energized and the shutter is
open. Never point the instrument at yourself or anyone else when the shutter is open and the
x-ray tube is energized. Never look into the path of the primary beam.
Your organization should establish, document, and follow a Radiation Protection Program.
An example of such a program can be found on the resource CD (provided with the
instrument).
Keeping your analyzer maintained in good condition will help minimize the risk of accidental
exposure. Mechanical malfunction of the shutter can be avoided by maintaining the
measurement window, as described in the User Guide. This prevents foreign objects from
entering your analyzer
Direct contact with the window could result in overexposures in the times indicated
below.

Extremity is defined by the NRC as the hand, elbow, arm below the elbow, foot, knee, or leg
below the knee. Whole Body is defined by the NRC as the head, trunk (including male
gonads), arms above the elbow, or legs above the knee.
As mentioned many times in this chapter, never place any part of your body in the path of the
x-ray beam. There is always a safe way to handle samples whether they are small, irregularly
shaped, or of low density. Never look into the path of the primary beam.
