[ RadSafe ] Fwd: Legacy school rad materials disposal

Marty's points are spot-on.  I'll go a step further, and suggest that
the regs governing the "distribution" and disposal of exempt
quantities, and generally-licensed RAM, can be gnarly, to say the
least.  Logic, as we might see it, is really neither here nor there.

I think that it would help the schools much, if they were to call a
friendly regulatory agent, on the RAM licensing side of the aisle, to
get the lowdown on how best to handle it, and what's permissible, and
what is not.  Or maybe a kindly consultant would donate some pro bono
advice to them (it's probably a tax write-off, what?).

I suspect that a 10 lb bag of phosphate fertilizer would exceed the
total activity of all the sets of materials as you've described. Also,
given that the ingrowth of progeny is minimal, that's less reason to
be concerned.

The quantity and concentration limits you refer to (DOT, IATA, IMDG etc) are used for transport of material - two different situations with different limits.
