Radium Franklin was a tugboat built in 1951, and operated by the Northern Transportation Company - popularly known as the "Radium Line", because many of their tugboats contained Radium in their name, since they were originally built to haul Uranium ore from Port Radium, on Great Bear Lake. She was retired in 1979, after spending most of her career hauling barge packed with ore, and then briefly serving as a yard tug.
