Refresher courses – Wednesday

08.30 hr – 09.30 hr

Tanja Perko

Participants will learn to develop a state-of-the science understanding of the individual, psychological, interpersonal and societal factors that influence the:

  • communication of radiological risk information during emergency and non-emergency periods;
  • impact of radiological risk communications on public’s risk perceptions, knowledge, attitudes, and behaviors;
  • apply this knowledge to designing effective risk communication and develop citizen-centered communication with the goal to empower citizens to make informed decisions in situations related to radiological risks;
  • become familiar with and practice methods for evaluating radiological risk communication efforts.

Course introduction

Whether you are dealing with radiation protection or application of ionizing radiation, it’s crucial to be able to communicate effectively to both the public and the media about risks, benefits of ionizing radiation or protection measures against radiation.

This refresher course will provide the latest science of radiological risk communication and skills needed to design effective radiological risks communication that improves outcomes, help key stakeholders make informed decisions, increase trust among stakeholders and cope with public anxiety. Good and bad communication examples, state-of-the-art ideas and ways to use them in radiation protection practice will be introduced.
