Which factor is key to reducing radiation exposure in medical practices?

Maintaining a safe distance from radiation sources is a fundamental principle of radiation protection known as the distance principle. This principle is based on the inverse square law, which states that the intensity of radiation exposure decreases with increasing distance from the source. As one increases the distance from a radiation source, the potential dose received decreases significantly, minimizing exposure risk to healthcare workers and patients.

In medical settings, maintaining appropriate distances is achievable through the careful positioning of both the patient and the equipment, ensuring that everyone involved is as far away as possible from radiation-emitting devices during procedures. This practice is an essential part of radiation safety protocols and guidelines to reduce the overall dose of radiation received by individuals in the procedure room.

This practice is not only effective in decreasing exposure but is also easier to implement compared to other options, such as adjusting equipment settings frequently or sedating all patients. These alternatives may not be practical or relevant for all situations and procedures. Hence, focusing on maintaining distance serves as a highly reliable and straightforward strategy for reducing radiation exposure.
