I also went to grade school in Yellowknife, so in some respects I came home after University (my family currently lives in Cambridge Bay, Nunavut). I am a currently a Professor in the Department of Earth Sciences at Simon Fraser University (SFU).
Living in the north is important to me because I want my daughter's native heritage to be passed on to her in a way that isn't available in southern Canada. Prior to my appointment at SFU in 1998, I was a Research Scientist employed by the Geological Survey of Canada.
Material giving rise to these enhanced exposures has become known as naturally occurring radioactive material (NORM).
Moreover, the maximum EISC and its isostatic footprint had a profound impact on the proglacial hydrological network, forming the and drained the present day Vistula, Elbe, Rhine and Thames rivers through the Seine Estuary. 14.6 ka BP, two major proglacial lakes formed in the Baltic and White seas, buffering meltwater pulses from eastern Fennoscandia through to the Younger Dryas when these massive proglacial freshwater lakes flooded into the North Atlantic Ocean.
Deglaciation temporarily abated during the Younger Dryas stadial at 12.9 ka BP, when remnant ice across Svalbard, Franz Josef Land, Novaya Zemlya, Fennoscandia and Scotland experienced a short-lived but dynamic re-advance.
The most important for the purposes of radiation protection are the radionuclides in the U-238 and Th-232 decay series.
For most human activities involving minerals and raw materials, the levels of exposure to these radionuclides are not significantly greater than normal background levels and are not of concern for radiation protection.
Independent glacio-isostatic modelling constrained by an extensive inventory of relative sea-level change corroborates our ice sheet loading history of the Barents Sea sector.
