How does increasing the distance from the radiation source affect exposure?

The correct answer is rooted in the principles of the inverse square law, which states that the intensity of radiation exposure is inversely proportional to the square of the distance from the source of radiation. As the distance from the radiation source increases, the amount of radiation that reaches a person decreases significantly.

For example, if you double the distance from the source, the exposure is reduced to one-fourth of what it would be at the original distance. This powerful principle highlights the importance of maintaining a safe distance from radiation sources in order to minimize exposure, which is a critical component of radiation safety protocols in dental practice and other fields involving radiation.

By understanding this concept, practitioners can effectively implement safety measures that protect themselves and their patients from unnecessary radiation exposure. This underscores the importance of proper training in radiation safety practices.
