Detailed explanation-1: -The strength of the X-ray beam is inversely proportional to the square of distance from the source (X).

Detailed explanation-2: -A greater distance from the radiation source can reduce radiation exposure. The amount of radiation exposure is not inversely proportional to the distance from the radiation source, but is inversely proportional to the square of the distance [2, 4].

Detailed explanation-3: -Specifically, an inverse square law says that intensity equals the inverse of the square of the distance from the source. For example, the radiation exposure from a point source (with no shielding) gets smaller the farther away it is. If the source is 2x as far away, it’s 1/4 as much exposure.

Detailed explanation-4: -The inverse square law states the the intensity of radiation decreases inversely with the square of the distance from the ionizing radiation source. This means that if the distance is doubled, the intensity decreases 4 fold. in other words, the intensity is one fourth the intensity if the distance is doubled.
