Section 20.3.7.703 - GENERAL TECHNICAL REQUIREMENTSA.Possession, use and calibration of instruments used to measure the activity of unsealed radioactive material. Other than unit dosages of beta-emittingunsealed radioactive material obtained from the manufacturer or preparer, licensed pursuant to Subsection J of 20.3.3.315 NMAC, a medical use licensee authorized to administer radiopharmaceuticals shall possess a dose calibrator, and use it to measure the activity of unsealed radioactive material prior to the administration to each patient or human research subject for diagnostic applications. For therapeutic applications, a medical use licensee authorized to administer radiopharmaceuticals shall possess a dose calibrator, and use it to measure the activity of unsealed radioactive material prior to and after the administration to each patient or human research subject.
