Hi, does anyone have a quick reference on the calculation for detector effective center, relating to proper distances for calibration.  Our cal source is getting weaker, and it is becoming a potential accuracy issue. My specific application is the typical 3" diam. cylindrical ion chamber, oriented vertically.  

Thanks for your help.
