The relationship between the intensity of radiation and distance is the
A)reciprocity law.
B)inverse square law.
C)direct square law.
D)15 percent rule.

Question

Quizplus · Accepted Answer

The inverse square law states that the intensity of radiation decreases proportionally to the square of the distance from the source. This means that if the distance from the source is doubled, the intensity of radiation will decrease by a factor of four. This law is important in radiation protection because it allows for the calculation of radiation doses at different distances from sources of radiation.
