Bill,

Excellent question. Did an inspector ever answer that question?
It's a ridiculous license requirement, in that if there is NO 
detectable activity, using standard state of the art detection 
instrumentation, then what purpose does requiring x number of half-
lives serve? Makes no sense, and appears that whomever wrote the 
license section doesn't understand radioactive decay, measurements 
and detection.
