I'm also Canadian, and have been entertaining the idea of (trying to) do my schooling in the US... Also, it's almost ridiculous to waste your time looking for a job in the Physics field within BC - open positions are few and far between.
Okay well, my friend just informed me that it is believed Ancient Egyptians used Uranium/Plutonium to rub over the wrappings, which may cause an issue with the particle decay of common C-14...
