What does the inverse square law state regarding radiation exposure?

The inverse square law describes the relationship between the distance from a radiation source and the intensity of radiation exposure. According to this law, the intensity of radiation exposure decreases as the distance from the source increases. Specifically, the law states that if you double the distance from the radiation source, the exposure received is reduced to one-fourth. This concept is crucial for radiological safety, as it emphasizes the importance of maintaining a safe distance from radiation sources to minimize exposure.

Understanding this principle is vital for radiological workers, as it informs practices around shielding and distance to ensure safety and compliance with regulatory standards. This is in contrast to the other options, which do not accurately reflect the behavior of radiation exposure relative to distance. The direct relationship or constancy implied in those options goes against the established mathematical relationship expressed by the inverse square law.
