Veterinary Uses of Nuclear Materials
Regulatory authority over the use of ionizing radiation in veterinary use is shared among several federal, state, and local government agencies. NRC (or the responsible Agreement State) has regulatory authority over the possession and use of byproduct or source material in veterinary medicine. Byproduct material is used in some calibration sources, radioactive drugs, bone mineral analyzers, portable fluoroscopic imaging devices, brachytherapy sources and devices, and teletherapy units used in veterinary medicine. Source material is used for radiation shielding and counterweights in therapy devices.
NRCs byproduct material veterinary use licenses are issued pursuant to NRC regulations in 10 CFR Part 30, "Rules of general applicability to domestic licensing of byproduct material." Because NRC has fewer veterinary licenses and does not have regulations specific to veterinary medical uses, it does not distinguish between different types of veterinary practices the way it does for medical use.
Veterinary use includes diagnostic, therapeutic, and research veterinary uses of radioactive drugs and devices. These licenses usually are issued for the treatment of domestic pets and non-food animals. At the present time, no radioactive veterinary drugs have been approved for use in animals intended for the human food supply.
Some veterinary practices only have regulated material in the form of prepackaged in vivo diagnostic test kits. The amount of nuclear material used these practices determines whether possession and use of the kits is authorized by specific license pursuant to 10 CFR Part 30 or a general license pursuant to 10 CFR 31.11. See the general license section for those materials generally licensed pursuant to 10 CFR 31.11. See 10 CFR 31.11, "General License for Use of Byproduct Material for Certain In Vitro Clinical or Laboratory Testing" for the registration requirements and the materials that can be used under this general license.
The Food and Drug Administration oversees the good manufacturing practices in manufacture of radio-pharmaceuticals, clinical tests materials and radiation-producing x-ray machines and accelerators. The states regulate the practices of veterinary medicine and pharmacy and administer programs associated with radiation-producing x-ray machines and accelerators.
