Re: Dose Rate From Scattered Radiation

[LIPTONW@dteenergy.com]

This type of calculation is frequently performed in designing medical x-ray 
facilities.  NCRP 49, "Structural Shielding Design and Evaluation for
Medical 
Use of X-Rays and Gamma Rays of Energies Up To 10 MeV", evaluates scattered 
radiation from Cs-137 (Ba-137m), starting on page 57.  I assume that other 
medical physics texts also cover this. 
 
The opinions expressed are strictly mine. 
It's not about dose, it's about trust.

I have been asked to calculate the dose rate from iron in a gamma 
ray beam (Cs-137).  I would like to make the calculation without 
going back to the Compton and Klein-Nishina equations.  Activity, 
distances and scattering angle are known. 
 
Surely this has been done before.  Any hints as to where? 
 
I will need references as this may go to court. 
 
Any help would be appreciated.  Meanwhile, I return to Compton, 
K-N and the basics.
