Observe the following rules for radiation protection of the
personnel in the examination room during X-ray exposures:
- Wear radiation protective clothing.
- Wear a personal dosimeter.
- Use the different recommended protective materials and
devices against radiation.
- While operating or servicing X-ray equipment, always keep
as large a distance as possible from the Focal Spot and X-ray
beam, never shorter than 2 meters, protect body and do not
expose hands, wrists, arms or other parts of the body to the
primary beam.
- Protect the patient against radiation outside the area of
interest by using protection accessories.
- Use the smallest X-ray field collimation. Make sure that the
area of interest will be completely exposed and the X-ray field
does not exceed the area of interest.
- Select a Focal Spot to patient skin distance as large as
possible to keep the absorbed dose for the patient as low as
reasonably possible.
The radiation dose decreases or increases according to the
Focal Spot to Receptor distance (SID: Source to Image
Distance): the greater the SID distance, the lower the
radiation dose. The radiation dose is inversely proportional
to the distance squared.
- Select as short an examination time as possible. This will
reduce total radiation dose considerably.
- Use Grids whenever possible.
- Place the region of interest as close as possible to the
image receptor. This will reduce exposure to radiation and
optimize the exposure.
- Be sure that audible and visual communication between
the patient and operator is established throughout the entire
examination.
