Operator Protection

2. Definitions Primary Radiation Secondary Radiation Scatter Radiation
The penetrating x-ray beam that is produced at the target of thee anode and exits through the tube head.
Primary beam
Secondary Radiation
X-radiation that is created when the primary beam interacts with matter (head, bones, teeth)
Less penetrating than primary radiation
Scatter Radiation
A form of secondary radiation and is the result of an x-ray that has deflected form its path by interaction with matter.
Deflected in all different directions
Most detrimental to the patient and the radiographer.

3. Protection Guidelines
RULE #1
****THE OPERATOR MUST AVOID THE PRIMARY BEAM****
Distance
Position
shielding

4. Distance Maintain adequate distance during exposure
Stand at least 6 feet away

5. Position Maintain proper positioning during x-ray exposure.
X-rays travel in a straight line
Stand perpendicular to the primary beam
90 degree angle-135 degree angle

6. Shielding
When ever possible stand behind a lead shield or lead lined wall. (protective barriers)
Wall can also be adequate protection if contains several layers of drywall.
