FW: [ RadSafe ] Recommendations on testing unknown waste

[Bryan Kirk]

Bob,

While I agree with the characterization, I would put in a qualifier that
the H-3, C-14, I-125 <0.05 uCi/g applies to scintillation material and
animal tissue, per the NRC regs.

There are two ways to characterize a waste for disposal:  knowledge of
the process that generated the waste or analysis of the waste. If you
know how it was generated, you can then conduct analyses to confirm that
it is what you think it should be from the process it came from.  If
lots of persons simply poured a variety of unknown solutions into a
drum, you will have to do analysis of a representative sample. If its
multilayered, you may have to pull a representative sample from each to
properly characterize. The initial tests should be those for
characteristics. The results of those tests will tell you if you need to
do more.

If the nuclides are H-3, C-14, or I-125, annd the activity is less than
0.05 microCi/gm, you may be able to dispose as hazardous only without
regard to the radioactive constituents.

Your message doesn't provide enough of the specifics to be able to
properly assist you.

Dear RadSafers,

I would appreciate your input on this matter.  We have radioactive
liquid waste, for which we know the activity and isotope, but the
chemical constituents are unknown.  My question is two-fold.  One, how
would one go about testing for the chemical constituents?  Is there a
laboratory that you would recommend?  Two, do we need to find and list
each chemical component, or can we just test the liquid by
characteristic/listed traits, and ship it as such (i.e.: Radioactive
material, flammable, n.o.s)?

You feedback would be appreciated.

Sincerely,

Depends on where you are located.? EPA has granted so relief on disposal
and storage of mixed waste.? However California did not adopt that
ruling and you still have to treat as radioactive and hazardous.? All
storage and time limits apply to mixed waste in California.
