1. The Inverse Square Law - Point sources of x- and gamma radiation follow the inverse square law, which states that the intensity of the radiation (I) decreases in proportion to the inverse of the distance from the source (d) squared: 2 1 d Iv This can be rewritten : 2 1 d I K where K is a constant of unknown value. So, for an intensity I 1 at ...
