RE: Shipping samples under DOT HM-230 Final Rule on Trasportationof Radioactive Material

["McLamb, John (NIH/NIEHS)" <mclamb1@niehs.nih.gov>]

The exception is built into the definition.



Under the new definition (below), the sample must be greater than BOTH the

concentration limit and the activity limit to be considered radioactive for

shipment.  For example a tritium sample would not be considered radioactive

if either the concentration is less than 27 uCi/g or the total activity is

less than 27 mCi.



	From Sec. 173.403  Definitions

	Radioactive material means any material containing radionuclides 

	where both the activity concentration and the total activity in the 

	consignment exceed the values specified in the table in Sec. 173.436

or values derived according to the instructions in Sec. 173.433.

Subject: Shipping samples under DOT HM-230 Final Rule on Trasportation of

Radioactive Material



After review of this rule, the change in definition of radioactive material,

would require Class 7 shipping requirements for samples previously not

regulated by DOT or NRC (2000 pCi/g)  for the purposes of shipment if the

concentration of the sample might exceed the exempt concentrations listed in

Table of Exempt Material (173.436).



Is there any exemptions for small quantities, such as soil samples and air

filters that have a chance of exceeding the exempt quantities?



Any help on this issue would be greatly appreciated.
