What is one effective method for reducing exposure during radiological procedures?

Increasing the distance from the radiation source is an effective method for reducing exposure during radiological procedures due to the inverse square law. This law states that the intensity of radiation decreases with the square of the distance from the source. Therefore, by increasing the distance from the radiation source, the radiation dose received decreases significantly. For instance, if you double the distance from a source, you only receive one-fourth of the radiation dose. This principle is fundamental in radiological safety practices, as it is often easier and more effective to manage exposure through distance than through other methods.

In contrast, options like decreasing the duration of exposure can be effective but might not always be feasible in practical situations. Wearing multiple layers of protective clothing can provide some level of shielding, but it is not as effective as utilizing distance. Using higher doses of radiological material would obviously increase exposure rather than reduce it, making it inappropriate in the context of minimizing radiation risks.
