This is true, but keep in mind that even if the contaminated area were 1
square centimeter, they could average over 300 square centimeters (and would
have gotten15 dpm/cm^2, for the 4440 dpm they found)...Given that they
reportedly wiped 2990 square centimeters, the entire external surface area of
the package, it is likely they actually wiped more than 300 cm^2...
This is one of those cases where it is conceivable that someone else taking
the wipe using the best possible procedures could have found 300 cm^2 with
more than 6600 dpm, but weighing the available information, it appears
unlikely. Keep in mind as well, this was a package containing Tc-99m...I
realize, the regulations don't distinguish on the basis of hazard per
isotope, nevertheless, this is a consideration in response to an incident.
