    Radiation risks and uncertainties : a scoping review to support communication and informed decision-making
    (2020) Hoti, Ferdiana; Perko, Tanja; Thijssen, Peter; Renn, Ortwin
    Although radiation protection is challenged by many uncertainties, there is no systematic study investigating the definitions and types of these uncertainties. To address this gap, in this paper we offer a scoping review to comprehensively analyse, for the first time, peer-reviewed scientific articles (n = 33) related to uncertainties in the following radiation exposure situations: nuclear emergencies, decommissioning of nuclear/radiological installations and long-term radiological exposure situations (e.g. naturally occurring radioactive materials). The results suggest that firstly, there is no agreement regarding definitions of uncertainty, which is mainly defined based on its sources, types or categories rather than by its meaning. Secondly, different actors are faced with different types of uncertainties. Uncertainties of the scientific community are mostly data and methodology-driven (e.g. dose-response relationships), those of the decision-makers are related to the likely consequences of decision options and public reactions, while laypeople’s uncertainties are mainly related to the trustworthiness of experts or the emotional potential of specific risk exposures. Furthermore, the majority of articles focus on the uncertainties of the scientific community, while those of the information receivers (i.e. decision-makers and laypeople) receive much less consideration. Finally, there was no difference in types of uncertainties across the different risk-related study areas analysed (radiation versus other risks). Based on these findings, we provide some preliminary recommendations regarding research on uncertainty related to radiation protection, as well as communication practices.

    Exploring smart grids with simulations in a mobile science exhibition
    (2015) Li, Huijie; Chabay, Ilan; Renn, Ortwin; Weber, Andreas; Mbungu, Grace
    Improving the publics' understanding of the energy system is a challenging task. Making citizens aware of how the complex energy system functions and how consumers of energy services can respond to a changing energy environment seems more difficult. In the context of the German energy transition, more active energy consumers are needed, not only in producing electricity on their own but also interacting with suppliers to make the energy system operate in a more efficient way through the development of a "smart grid". This article describes an approach taken with a public education perspective to engage citizens in thinking about the issues we are facing in moving toward a future with greater reliance on renewable energy. We introduced a mobile exhibition, including an interactive simulation game, which offered a perspective on the whole energy system. The goal was to stimulate questions and arouse citizens' interest in learning about the smart grid and help them to prepare for the transition to a smarter way of using energy.
