Target: Material containing U-235 that is designed to be irradiated in a nuclear reactor.
Target cladding: Target encapsulation of aluminum or stainless steel that serves to protect the chemically reactive uranium metal or alloy and to contain the fission products produced during irradiation.
Target meat: Uranium-bearing material in the target.
Tc-99m kits: Chemicals (e.g., pharmaceutical agent, chelating compound, and saline solution) used to formulate a radiopharmaceutical to which Tc-99m is added.
Technetium generator: Device used to store Mo-99 and extract its decay product Tc-99m.
Technetium generator curies: Calibrated quantity of Mo-99 based on the number of curies that are contained in the generator on the day of or day after its delivery to the radiopharmacy, hospital, or clinic.
Thermal neutron: Low-energy neutron of about 0.025 electron volts at room temperature.
Tracer testing: Evaluation of the separations methods and processing of targets using very small amounts of radioactive material.
