Decayed, Effective and Residual Radioactivities of Selected ^99MTC-Labelled Radiopharmaceuticals and Their Implications for Nigerian Nuclear Medicine Practice

The need for more formal documentation of nuclear medicine practice around the world has been highlighted by some authors. It has also been suggested that data should be collated from different operational facilities to establish more specific Diagnostic Reference Levels (DRLs) so that practice in different jurisdictions can be properly regulated. The Nigerian practice is beleaguered by a myriad of challenges that force frequent operational disruptions, and consequent paucity of research. The country's regulatory bodies have not yet recommended any DRL for the Practice. The IAEA recommends that administration of radiopharmaceuticals should closely follow their preparation. The presentation therefore aimed to report the radioactivity levels of frequently used radiopharmaceuticals in the Nigerian Practice, suggest modifications where necessary, and provide guidance levels.
