Probably because under the "old" U.S. DOT regulations (before
10/1/2004), anything over .002 uCi/g was considered radioactive material
for transportation purposes; material having a lower specific activity
was exempt from regulation as a hazardous material.  Of course use of
that limit today has no regulatory basis.

recently eBay the online auction site has "banned radioactive" items
their site. In a recent letter to a person offering unprocessed ores on
the site 
 (a seemingly common practice) the following statement was made  by
"Please also remember that anything that has a specific activity greater

than 70 Bq per gram (.002 microcurie per gram) is not permitted on eBay
any conditions."
So to that end I pose this question. Why the above "limit" what makes 70
the "magic number" or rather might there be a "scientific basis for such
