The Radioactive element Radium was discovered by “Marie Curie” on December 21, 1898. She was the first women to win a ‘Nobel Prize’ as well as the first person and the only women to win the Nobel Price ‘twice’.
This radioactive element Radium was discovered a few months after she discovered ‘Polonium’. She measured the intensity of Radium at around 3,000 times more than ‘Uranium’.
The Radium was used in Radiotherapy and Nuclear Medicines, which were used in the treatment of Cancer and other diseases. The excess or regular contact with Radium causes ‘Radiation Poisoning’. Marie Curie during the research time was in contact with the element for a longer period of time which affected her health. After spending her maximum time with elements and researches, the overexposure with radiations killed her on July 4, 1934.
