rule of thumb

[Michael McNaughton <mcnaught@lanl.gov>]

Dear radsafers

can you point me to a derivation of the rule of thumb for the gamma dose
rate in an infinite medium or solution: dose rate (rad/h) = 2.12 EC/rho; it
is listed on pages 52 and 54 of the Rad Health Handbook, (1992 edition).

Thanks, mike
