Climate change is an issue affecting all of us now and in the future. Partially driven by emissions of carbon into our atmosphere by traditional sources of electrical power (coal, oil, natural gas), climate change can be reduced by more “green” power sources (wind, solar, nuclear). Nuclear power has zero carbon emissions but many fear it because of real or imagined releases of radiation to the public. This presentation attempts to explain what radiation is, how it affects us all, how it is related to nuclear reactor accidents and to nuclear power itself. Please come with questions of all kinds!
