...Other radium deposits exist in Czechoslovakia, Belgian Congo, Portugal, Australia, Colorado, Utah. The deposits in Czechoslovakia are almost depleted. Since the discovery of the rich Belgian Congo deposits in 1922, the U. S. production has almost ceased. Up to 1929, because of the great labor and expense involved, only 300 grams of radium had been produced, an insufficient supply for medical men and watchmakers...
...Because radium is one of the most useful and expensive things in the world, the discovery of even a small new source is more important than the discovery of fields of gold. Last week despatches from Ontario announced that Canadian mine experts had found a. radium mine near Wilberforce. Three years ago miners in the district discovered traces of uraninite (uranium oxide) in pegmatite, a type of rock rich in valuable minerals. Where there is a uranium deposit, mine experts have learned to look for radium. Uranium, producer of radium, is constantly emitting rays, changing its internal structure until...
Soon as news of the discovery spread, people came running with money to buy the mine. One gram of radium sells to-day for from $50,000 to $70,000. A group of Canadian doctors finally succeeded in buying several hundred acres around the discovery. Headed by Dr. Gordon Earle Richards, head of the X-ray department, Toronto General Hospital, and Dr. George William Ross, they organized Ontario Radium Corp. Last year they sent samples of their ore to England. There it was refined, meeting satisfactorily all necessary tests. The doctors found that one ton of their ore yielded...
...reduce cancer mortality* the public must be taught to go to a doctor the instant some physical abnormality appears, and that doctors must be taught to recognize the early stages of cancer. If cancer is caught at its initial appearance it can usually be cured by surgery or radium...
...There is no question but that the X-ray tubes can be materially improved and made more powerful. We now produce X-rays of from 6,000 to 250,000 volts and, if we went to 400,000 volts, we could get practically radium rays from an X-ray tube. We know results would be better. But we cannot go that high, for we lack tubes to stand it, and so far no one has dared to tackle their development because of the patent monopoly...
