Re: ram in transit



  In a previous life (pre '78) I was involved with shipping radionuclides.
Trucks transporting the boxes to the airport had to be labeled on the sides
and back.  I am still seeing trucks with such labels, mainly soil testing
operations.  There was a limit on the number of transport indexes that could
be loaded on a truck without meeting special requirements. If I remember
correctly the TI for a package was the radiation level at 1 meter from the
package.  The maximum alowed values were 200 mr/hr on contact and 10 mr/hr
at 1 meter.  Is this now ancient history?
