Pharmacists became involved in the synthesis of 18F-FDG and its quality control after our hospital opened a PET center on April 1, 2005. This work involves the use of high-dose radioisotopes and has raised concerns regarding the possibility of pharmacists being exposed to radiation in the hot lab. We created a dose-rate distribution map for the hot lab and determined radiation exposure doses at various points to investigate ways of minimizing radiation exposure during work procedures. The map enabled us to know the locations in the hot lab where there is a strong possibility of being exposed to high dose radiation, giving us a good starting point for considering countermeasures.
