Which method is best to minimize radiation exposure during fluoroscopic procedures?

Maintaining a safe distance is the best method to minimize radiation exposure during fluoroscopic procedures. The principle behind this is based on the inverse square law, which states that the intensity of radiation exposure decreases significantly with increasing distance from the radiation source. By increasing the distance between the patient, the fluoroscopy tube, and the staff or any individuals involved in the procedure, the radiation dose received by those at greater distances is substantially reduced.

This approach is particularly effective because even small increases in distance can lead to a large decrease in exposure. For example, doubling the distance from a radiation source can reduce the exposure to one-fourth of the original level. This practice is a fundamental aspect of radiation safety protocols and is widely recommended in medical settings to protect both patients and healthcare providers from unnecessary radiation exposure.

Other methods, while perhaps relevant in certain contexts, do not provide the same level of efficacy in minimizing radiation exposure as maintaining distance does. For instance, increasing the dose rate would actually raise radiation exposure, and using a grid, although helpful in improving image quality, does not inherently reduce the amount of radiation delivered. Avoiding the use of shielding can be counterproductive, as shielding is a protective measure that can help absorb some of the radiation, thus reducing exposure to those
