Radiation protection is an important task for nuclear medicine departments with regard to the use of radiopharmaceuticals for diagnostic and therapeutic purposes. It is important to make sure that the radiation dose to the patients as well as to staff members is kept “as low as reasonable achievable” (ALARA). In the last few years, the use of PET substances with higher photon energy than the previously used radionuclides has been more and more common, and the number of PET radionuclides is increasing. There is a sudden appearance of multimodal PET/CT and SPECT/CT scanners.
