A clinician would receive 1 rad of radiation from a distance of six feet.
Radiation intensity is inversely proportional to the square of the distance from the source of the x-rays. The original intensity of 4 rad divided by the square of six (distance in feet) is proportional to 1 rad over the original distance of three (feet) squared.
