Re: Technical basis for 100 cm^2



     What do you mean by "Rickover Days"?  It wasn't that long ago. Or was 
     it?  I'm glad to see someone still remembers the basic training.

To the best of my knowledge, I think the technical basis for using 100 cm^2 
when surveying for loose contamination comes from Naval Nuclear Power, during 
the "Rickover Days", and is based on the following: 
     
 (1) Smears tend to disintegrate when surveying areas greater than 100 
cm^2.   (the original smears were paper chemistry filters) 
     
 (2) 100 is a convenient number to use when performing calculations in 
your head. 
  (RadCon Math) 
     
 (3) 100 cm^2 is approximately the area of clothing that would be 
contaminated if   a individual brushed against a contaminated 
surface. 
     
I hope this info can help.
