How does increasing distance from a radiation source affect exposure?

Increasing distance from a radiation source minimizes radiation exposure due to the inverse square law, which states that the intensity of radiation from a point source decreases with the square of the distance from the source. As you move farther away, the radiation spreads out over a larger area, resulting in a lower dose received by an individual. This principle is fundamental in radiation safety and is applicable to all types of radiation, not just high-energy sources.

Distance is a critical factor in reducing exposure; therefore, maintaining a safe distance is one of the most effective strategies for protecting oneself from radiation. This effect is consistent regardless of the energy of the radiation source, underscoring the importance of distance in radiation safety protocols.
