Answer: One means of enriching uranium is by diffusion of

Chapter 9, Problem 57GP

(choose chapter or problem)

A shielded \(\gamma\)-ray source yields a dose rate of 0.052 rad/h at a distance of  for an average-sized person. If workers are allowed a maximum dose of  in 1 year, how close to the source may they operate, assuming a 40-h work week? Assume that the intensity of radiation falls off as the square of the distance. (It actually falls off more rapidly than \(1/r^2\) because of absorption in the air, so your answer will give a better-than-permissible value.)
