Also, you state that prior testing\nin the United Nations Manual of Test and Criteria, \"Classification Procedures, Test Methods and\nCriteria Relating to Oxidizing Substances for Division 5.1.\"\nBased on the information you provided, we concur that if the material meets the definition of\nLow Specific Activity (LSA) as defined in 49 CFR 173.403 and does not meet any other hazard\nclass, it would be most appropriately described as \"Radioactive material, LSA, n.o.s.\"\nI hope this information is helpful. Should you have further questions, please contact us.\nSincerely,\nHille 2. Mthele\nHattie L.

The thorium in this material has the naturally\noccurring isotopic distribution and has not been irradiated or isclopically concentrated\nThe DNSC is considering transporting this material as part of a final disposition pian. Some\nprior testing of this material, performed at the direction of DNSC, indicates that the 5 hydrate\nform of thorium nitrate will not qualify as an oxidizer under the test protocol provided in the\nUN Manual of Test and Criteria \"Classification Procedures, Test Methods and Criteria Relating\nto Oxidizing Substances for Division 5.1\". If the UN Manual of Test and Criteria\n\"Classification Procedures, Test Methods and Criteria Relating to Oxidizing Substances for\nDivision 5.1\" test protocol is performed on a representative sample of the Th(NO3)4 • 5H20 in\nthe DNSC inventory and the material does not qualify as an oxidizer, can this material be\nclassified, packaged, and shipped as \"Radioactive materials, LSA, n.o.s\"?\nSincerely,\n(\nE KEVIN REILIX/\nDirector,\nDirectorate of Environmental Management &\nQuality Assurance\nFederal Recycling Program\nPrinted on Recycled Paper","truncated":false,"body_characters":3269}
