Skin Dose from Multiple Plane Sources



     I am looking for a broad cross section of opinions on the following 
     subject. I have received a couple of different opinions and I also 
     have my own.  I am hoping that if enough opinions are expressed that 
     we should statistically gravitate toward the true answer (interesting 
     concept, huh?).
     
     If a person has multiple plane sources on the same organ (i.e. 
     SDE,WB), how should the dose be reported?
     
     a. Add the cumulative dose from both plane sources since they are both 
     supplying dose to the same organ (skin)
     
     b. Take the highest dose calculated of the two and use it to represent 
     the entire contamination event.
     
     c. Calculate the dose to 1 cm^2 of skin from the highest detector 
     reading (i.e. 15.5 cm^2 GM) and use it to represent the entire 
     contamination event.
     
     
     
     Please feel free to refer to existing reference documents, none of 
     which I have yet to find.  This is a serious enquiry and I would be 
     more than happy to keep statistics and references based upon responses 
     and later repost the results.  I have my own opinion, but I wouldn't 
     want to bias any of the responses.
