It is worth recalling the history of this treatment, which began when American, James Douglas, discovered extensive pitchblende deposits on his Western mining properties. |
More illusive than gold and many times more precious, radium, the product of pitchblende, had somehow gotten into his blood. |
During the early years of radium and uranium refinery operations in Port Hope, highgrade pitchblende ores were processed. |
The hint of a new element in pitchblende materialized in July 1898, when the couple reported gathering a substance that was 400 times more active than metallic uranium. |
It was a waste product from the production of radium from the pitchblende deposits around Great Bear Lake in northern Canada. |
The first discovery of pitchblende in the United States was associated with gold ores at the Wood mine in Gilpin County. |
