Nine Facts You Need to Know
about Uranium Mining
UPdate Fall 2008
1. “Uranium mine tailings are among the most difficult to manage wastes
on the planet… They contain toxic substances, particularly heavy metals.
About 85 per cent of the radionucleides from the ore end up in the tailings,
so it's radioactive. They're typically acidic and semi liquid and hard to contain. … In
the Maritimes, because you'd be dealing with relatively low-grade ore, you'd
tend to produce more tailings per tonne of ore."
Mark Winfield, Assistant Professor of Environmental Studies, York University,
2. “In Nova Scotia, the wet climate, generally high water table, and
generally acidic waters may pose special problems to radioactive waste management.”

3. Once groundwater is contaminated from uranium mine tailings, is impossible
to undo the damage. 1% of wells in NS already contain levels of uranium above
the limits considered safe, from naturally occurring uranium in rock.
4. “In Canada, a walk away solution is not realistic for decommissioning
most uranium tailings sites. Long-term storage requires long-term institutional

5. Surface mines can generate up to 40 tonnes of waste rock for every tonne
of uranium ore produced, while underground mines produce about one tonne of
waste rock per tonne of ore. There are 109 million tonnes of waste rock from
uranium mining in Canada today.

6. Supplying a typical Canadian household with nuclear-generated electricity
results in the production of 14kg of toxic and radioactive mine tailings and
up to 440 kg of waste rock every year. These wastes continue to release radioactive
elements for thousands of years.
7. “Whether or not [uranium] mining is conducted in open pits or underground,
there are environmental health hazards and impacts to workers and the general
public that need to be considered. These include radiation hazards from radon
gas, radium, thorium, and non-radioactive contamination from dust and heavy
metals such as arsenic, lead, and nickel.”

8. Radiation is one of the few exposures for which the cause-effect relationship
with childhood leukemia has been established (Belson et al. 2007). Children
are 20% more sensitive to radioactivity because their cells are actively dividing.
9. Residents living near uranium mining operations have a higher risk of genetic
damage than people living further away.
