Nuclear pharmacy involves the preparation of radioactive materials for diagnosis and treatment in nuclear medicine. Pharmacists working in nuclear pharmacy are responsible for calculating dosages, ordering, transferring, transporting, and dispensing radiopharmaceuticals using protective measures. Radiopharmaceuticals must be stored, distributed, and transported according to strict safety regulations due to their radioactive nature. The role of the nuclear pharmacist is important for ensuring radiopharmaceuticals are properly prepared and administered to patients.
