Evolution of the Health Canada astronaut biodosimetry program with a view toward international harmonization

The complexity of damage that results from protracted, non-homogeneous radiation exposure, like that found in the space environment, requires a detailed scoring schematic to capture as much information as possible. To that end, this paper outlines the efforts to harmonize the manner in which Health Canada's FISH data are recorded to better facilitate the comparison of results with other international biodosimetry programs.
