Answering the Inverse Square Problem

The inverse square problem in our recent post asked a question that all RT techs should be able to answer.

It not only applies to technique development, but also safety. Since the intensity of radiation is inversely proportional to the square of the distance, the answer is as follows: If I1 = 28 R, I2 = 2R, D1^2 = 9 feet, then D2^2 = 11.2 feet.
