An Experimental Dispensing System for Withdrawal, Preparation, and Assay of Tc-99m Radiopharmaceuticals

Abstract

Radiation exposures to the fingertips and hands of technologists were monitored as they prepared radiopharmaceuticals using an experimental dispensing system. Results were compared to those obtained by conventional syringe shields. Our study assessed the overall exposure levels received during each phase of radiopharmaceutical preparation. We describe the speed and ease of our experimental dispensing system; most importantly, we report a reduction in radiation exposure to the fingertips and hands of personnel as measured by thermoluminescent detector chips.
