i However, since the charcoal cartridges used to capture airborne I-131 were counted in batch mode, that is more than one at a time, it is possible that approximately 10% of the samples did not attain the 3

designLLOof0.07pC1/m,tneaveraegl0ofthese cartridges was approximately 0.09 pC /m.

It should be noted that charcoal cartridges are routinely-analyzed from nine locations, the ODCH requires only five.
