At what angle should the operator stand from the x-ray beam during an x-ray exposure?

The operator should stand at an angle of 90 to 135 degrees from the x-ray beam during an x-ray exposure to minimize exposure to scattered radiation. This angle allows the operator to be in a position where the intensity of radiation is significantly reduced compared to areas directly in line with the beam or immediately adjacent to it.

When considering radiation safety, standing at this angle provides optimal protection because the radiation scatter decreases with distance and at specific angles. At approximately 90 degrees, the exposure is at its lowest because the operator is not in the direct path of the primary beam or its direct scatter. Furthermore, extending this angle to 135 degrees further reduces exposure due to the increasing distance from the primary beam.

Angles outside this range may not provide the same level of safety, as they could expose the operator to higher levels of scatter radiation. This understanding of safe operating positions is crucial for minimizing health risks associated with radiation exposure during x-ray procedures.
