Radiation Protection in Nuclear Medicine: Best Practice

15 March 2022


Moderator: Jenia Vassileva (IAEA)

Presenters: Sigrid Leide-Svegborn (Sweden)


In the modern diagnostic and therapeutic nuclear medicine, radiopharmaceuticals are successfully used for the diagnosis and, increasingly, for the treatment of diseases. Despite the increasing benefit for patients from the nuclear medicine technologies, their use pose a radiation health risk for those who are exposed, especially when radiation protection guidance and principles are not properly implemented.

Three different types of exposure can occur in nuclear medicine: medical, occupational, and public. Medical exposure applies to patients of various ages who benefit from the diagnostic or therapeutic procedures for which they are referred to diagnose or treat diseases such as cancer, cardiovascular diseases and many others.  Included in this group are also carers and comforters as well as volunteers in biomedical research. The second group includes occupationally exposed personnel working in a nuclear medicine practice, and the third group are the members of the public.

The goal of radiation protection in nuclear medicine is to ensure that the expected medical outcome for the patient is achieved, and procedure optimized while limiting the radiation risk to the patients, medical personnel and public.

The aim of this webinar is to provide knowledge of the radiation exposure of members of these groups, to provide  information and advise on how to optimize the use of the radionuclides and to highlight some of the tools and measures that need attention as they contribute to  limiting the radiation dose. Examples of good practices will also be discussed  on the management of the radionuclides in a clinical nuclear medicine facility.

Learning Objectives

  • To get information about radiation exposure of different exposed groups, due to the use of radiopharmaceuticals in diagnostic and therapeutic nuclear medicine.
  • To learn how to optimize the management of radiopharmaceuticals in order to limit the radiation dose of various groups of exposed individual.
  • To get information on different radiation protection tools and measures in order to minimize unnecessary radiation dose.


Sigrid Leide-Svegborn is an Associate Professor in Medical Radiation Physics at the Department of Translational Medicine, Lund University, Sweden, and Senior medical physicist (medical physics expert) at Skåne University Hospital in Malmö, Sweden. She is a member of the International Commission of Radiological protection (ICRP) Task group “Radiation Dose to Patients in Diagnostic Nuclear Medicine,” and a member of the European Association of Nuclear Medicine (EANM) committee on radiation protection. She has more than 25 years of clinical experience as a nuclear medicine physicist and nearly 50 publications concerning radiation protection of the nuclear medicine patient and personnel.
