Radium was eventually banned after scores of dial painters died from cancer and various ghastly ailments . ... One study by the Public Health Service many years ago found that a person who wears a radium watch for 24 hours a day over the course of a year could conceivably be exposed to 65 to 130 millirems of radiation.
When was radium banned?
Eventually, scientists and medical professionals realized that these workers’ illnesses were being caused by internal contamination from the radium they ingested. By the 1970s , radium was no longer used on watch and clock dials.
When did they realize radium was dangerous?

Did Marie Curie know how dangerous radium was?
Unfortunately, the Curies had no idea of the dangers inherent in exposure to radioactive elements. In fact, her husband carried a sample of radium in his pocket, so he could show people how it glowed and emitted heat.
What’s more dangerous uranium or plutonium?
Plutonium-239, the isotope found in the spent MOX fuel, is much more radioactive than the depleted Uranium-238 in the fuel. ... Plutonium emits alpha radiation, a highly ionizing form of radiation, rather than beta or gamma radiation.
Can radium be removed from the body?
No more than 20% of the ingested radium is absorbed from the digestive tract and distributed throughout the body. The rest is excreted unchanged from the gut . Some absorbed radium is excreted in urine.
