DOT SURVEYS

[James Reese <jreese@smtpgate.ddrw.dla.mil>]

     Radsafers,
     
     As I understand the DOT and NRC regulations, the contamination limits 
     for receipt surveys of packages are listed "per 300 cm sq".  What is 
     the accepted interpretation of this limit:
     
                a.  Does it mean that the surveyor must survey at least 50 
     cm sq over the 6 sides of a boxed package?
     
                b.  Does it mean that the surveyor can survey 100 cm sq and 
     relate the results to 300 cm sq equivalent?
     
                c.  Does it mean that the surveyor can survey 300 cm sq on 
     the side of the package most likely to indicate contamination?
     
                d.  None of the above
     
     Thanks in advance for your assistance.
