Introduction
Take a moment and list off the nuclear issues in Canada you are aware of: radioactive waste, medical isotopes, radioactive leaks and new nuclear reactors will come to mind. The media reports on little more. Few Canadians know how many communities and environments have been contaminated forever by the nuclear industry. Even fewer know the number of radiation-induced illnesses and premature deaths the Canadian Government has knowingly caused through its actions and inactions.
These papers list a wide range of nuclear issues and situations that have been caused and, for the most part hidden, by the Canadian Government since their involvement in nuclear weapons and nuclear electricity generation began 65 years ago. The government's current attempt to expand their involvement into all parts of the nuclear fuel cycle is particularly frightening.

Human Health Implications of Uranium Mining

Uranium mining, in particular open pit mining, , involves digging thousands
of tons of radioactive rock out of a giant hole. Large quantities of
this rock are dumped onto the earth’s surface. The ore is then transported to
a milling facility, usually nearby, and crushed to a fine sand-like consistency,
creating radioactive dust and finely ground mill tailings. The uranium is
separated out, usually with strong acids or alkalis. The sand-like tailings,
containing about 85% of their original radioactivity, and often the chemicals
used in the extraction process, are deposited in large tailings ponds or
containments nearby.
Dust containing uranium and its progeny is produced in large quantities by
rock-crushing operations. This particulate matter, containing long-lived
radioactive isotopes, can leave the site on wind. Wind erosion of tailings piles
can be significant as long as these remain exposed to weather. Radon gas is
continuously produced by the decay of thorium 230, a radioactive decay
product of uranium 238, through radium into radon. Thorium 230 has a halflife
of 76,000 years, and will produce radon gas unabated for millennia.
Groundwater and surface water in the vicinity of uranium mining operations
frequently become contaminated (31). At the advanced exploration stage of
mine development, holes about 1-2” in diameter and up to 1200 feet deep
are drilled into rock, usually into the most concentrated deposits. A hole of
this depth is almost certain to penetrate aquifers, giving water access to
radioactive rock surfaces. Many uranium compounds and decay products are
soluble, toxic and radioactive. In an area of fractured granite bedrock, as
found in some uranium bearing areas of Ontario, many of the aquifers
interconnect and contamination quickly becomes widespread.
Uranium is a heavy metal which means that it is toxic in addition to its
radioactivity. In drinking water, at levels in excess of the safe drinking water
standard of .02 mg/L or 20 ppb, it is principally toxic to the kidney, in
particular the proximal tubules (32). Uranium can also affect fertility, fetal
growth and postnatal viability (33). It may cause malformations in fetuses
and might be associated with reproductive cancers. It concentrates in bone
and may interfere with the activity of osteoblasts, possibly contributing to
bone cancers and osteoporosis (32).
What are the risks from these tailings? According to the CAIRS study, a
person walking over a typical tailings pile for 1 hr every day will absorb a
gamma radiation dose of, on average, 0.73 mSv/yr (41). This would be in
addition to the ~1.0 mSv/yr of background gamma radiation we all receive.
Consider that doubling a person’s exposure will in general double his/her
cancer risk, and that this person will also be exposed to higher than normal
levels of radon gas near the tailings.
