"Considering Ecosystem Approaches to Characterize Effects of Ionizing Radiation, Including Changes in Ecosystem Services", in [5 | Environmental Risk Assessment]

Chairs: Lawrence Kapustka, Carmel Mothersill

Description: Over the past decade, members of the International Union of Radioecology and SETAC have explored the rationale for using an ecosystems approach to evaluate the effects of ionizing radiation in various settings. These settings range from mining sites where radioactive minerals are extracted, to processing sites, nuclear power plant emissions, and accidents. The focus of these efforts has been to provide greater ecological realism to the evaluations, especially in areas characterized by having complex social-ecological systems. In addition, the ecosystem approach is aligned with the stated protection goals and so provides better information to decision makers than the traditional reference animal and plant (RAP) approach.
Members of the IUR-SETAC working group have conducted laboratory and field studies on mechanisms of action, environmental distribution of radionuclides, measures and projection of received doses in plants and wildlife, as well as social implications of radiation releases into environments. In every instance where there are releases of ionizing radiation into the environment, there are many other stressors that influence the severity of outcomes. Projecting risks, or alternatiely managing for safety, requires consideration of changes in climate, severity of storm events, co-contaminants, and land use practices of the associated human communities.
In this session, we are seeking laboratory or field studies as well as theoretical studies that advance our collective knowledge toward protection of human and ecological receptors that may be exposed to ionizing radiation. This includes studies that provide information about changes in ecosystem services resulting from exposures to ionizing radiation.
Keywords: Combined Exposure / Mixtures / Multiple Stressors. Ecosystem Service.
