A shielded -ray source yields a dose rate of at a distance
Chapter 31, Problem 60(choose chapter or problem)
A shielded -ray source yields a dose rate of at a distance of 1.0 m for an average-sized person. If workers are allowed a maximum dose of 5.0 rem in 1 year, how close to the source may they operate, assuming a 35-h work week? Assume that the intensity of radiation falls off as the square of the distance. (It actually falls off more rapidly than because of absorption in the air, so your answer will give a better-than-permissible value.)
