 I must disagree, to average a contamination reading over 300 cm^2 if the
 package were only 1 cm^2 just to get a lower mathematical value, should be
 incorrect.  I don't see how you can take credit for an area you did not
 assess.  I believe 49CFR says "the radioactivity is averaged over the
 surface wiped", not just divide by 300 cm^2.
 
 How would others handle items less than 300 cm^2? >>

No, no, no....If the PACKAGE were only 1 cm^2, you are right, it would not be 
appropriate, BUT if the package is 1000 cm^2, and the CONTAMINATION is only 
in 1 cm^2, you CAN average over 300 cm^2, assuming you KNOW by some means 
that the contamination you actually measured was restricted to the 1 cm^2 
area.
