Canadian Standards Association (CSA) N288.2

December 2014

Project Summary

The Canadian Standards Association (CSA) contracted International Safety Research (ISR) to re-write their guidelines for calculating radiation doses based on a release of airborne radioactive material to capture advances made in the fields of atmospheric dispersion modelling and dose assessment. ISR conducted a literature search and consulted with industry experts to identify a clear and concise guidance on treatment of meteorology, source characterization, modeling atmospheric dispersion, calculation of consequences and model uncertainties. This project incorporated the above findings into a current standard for modelling the consequences of a nuclear reactor accident in Canada. This standard identifies acceptable data sources and methodologies to account for specific effects, and recommends standardized end points for the calculations in determining dose rates. The produced standard is now available on the CSA Standards website.
