Hello,

I have a question regarding the definition of Radioacive material in 49 CFR
Part 173.403.  If the specific activity is greater than 2 nCi/g, then it is
radioactive.  

When determining specific activity, what can you average this over?  Is it
just the source/sources inside or the entire contents and container?
Sincerely,

Tim Paul, MS, CHP
