The principle behind increasing distance for radiation workers is based on which law?

The principle of increasing distance for radiation workers is fundamentally based on the Inverse Square Law. This law states that the intensity of radiation from a point source diminishes with the square of the distance from that source. In practical terms, as the distance between a radiation source and a person increases, the amount of radiation exposure decreases significantly.

For instance, if a worker doubles their distance from a source of radiation, the intensity of exposure is reduced to a quarter of what it would be at the original distance. This principle is vital in radiation safety protocols, encouraging workers to maintain as much distance as possible from radiation sources to minimize their exposure and reduce health risks associated with radiation.

The other options, while related to the broader concepts of physics and safety, do not specifically describe the relationship between distance and radiation intensity in the same way that the Inverse Square Law does.
