Mining uranium: how safe is it and why do it? Myths

2020-11-4  Myth 4. Working in uranium mining is the path to death "No, it doesn't correspond to reality, because what we extract is closer to the background. That's what we experience in our daily life when we sit on granite, for instance. Granite indicates some level of radioactivity. It has a natural radiation background. With mining uranium, it's the same.

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.
