Dr. Carmel Mothersill is a radiobiologist and Canada Research Chair in Environmental Radiobiology. Her interests are in the impacts of low dose and chronic radiation exposures on non-human species and on ecosystems. She is developing biomarkers which can indicate effect (harmful or beneficial) at the level of the population, community or ecosystem. Such biomarkers will hopefully be used to aid decision making about the risks of radioactive releases in environmentally sensitive areas. Many of the system level markers identified so far relate to stress responses and immune responses which can be compromised by low level radiation exposures.
