What is a common way to minimize radiation exposure during medical procedures?

Increasing the distance from the radiation source is a well-established principle in radiation safety known as the inverse square law. This law states that the intensity of radiation exposure is inversely proportional to the square of the distance from the source. By doubling the distance from the radiation source, the exposure is reduced to a quarter of what it would be at a closer distance. This is one of the most effective ways to minimize radiation exposure because it significantly decreases the amount of radiation that reaches a person.

In medical settings, maintaining an appropriate distance can protect both patients and healthcare workers from unnecessary radiation. It emphasizes the importance of positioning and using equipment designed to allow for maximal distance between the source of radiation and those involved in the procedure.

Other methods, such as using lead aprons for shielding or optimizing imaging protocols to reduce the frequency and duration of exposure, are also important, but increasing the distance is a primary strategy that directly impacts safety.
