Abstract
This teaching editorial was written by members of the Canadian Advisory Committee on Radiopharmaceutical Quality Assurance in Nuclear Medicine. The committee is an advisor to the Health Protection Branch, Health and Welfare Canada, on radiopharmaceutical quality assurance. At its annual meeting, the Committee recognized the need for a two-part reference article which would provide the nuclear medicine community with a basic discussion on facility and equipment requirements and concepts and techniques of universal precautions, aseptic technique, and radiolabeling for those departments currently performing or planning to start cell radiolabeling procedures.
