Dear Mr. Reilly:

This is in response to your February 21, 2001 letter, inquiring whether your thorium nitrate hydrate may be offered for transportation as "Radioactive materials, LSA, n.o.s." under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).

You state that because of its highly hydrated state, the material has solidified into a non-friable rock-like monolith mass inside the packages during storage. Also, you state that prior testing indicate the material does not meet the defining criteria for a Division 5.1 under the test protocol in the United Nations Manual of Test and Criteria, "Classification Procedures, Test Methods and Criteria Relating to Oxidizing Substances for Division 5.1."

Based on the information you provided, we concur that if the material meets the definition of Low Specific Activity (LSA) as defined in 49 CFR 173.403 and does not meet any other hazard class, it would be most appropriately described as "Radioactive material, LSA, n.o.s."

I hope this information is helpful. Should you have further questions, please contact us.

Sincerely,

Hattie L. Mitchell
Chief, Regulatory Review and Reinvention
