WebIn 1898, the discovery of two new elements, polonium and radium, reawakened interest in the topic of uranic rays discovered 2 years before by H. Becquerel. Radioactivity, a name coined by Marie Curie, became a major research field for decades. WebThe first element to be discovered by radiochemical analysis, polonium was discovered in 1898 by Pierre and Marie Curie, who were investigating the radioactivity of a certain pitchblende, a uranium ore. The very intense …

The Nobel Prize Women who changed science Marie Curie

WebIndefatigable despite a career of physically demanding and ultimately fatal work, she discovered polonium and radium, championed the use of radiation in medicine and fundamentally changed our understanding of radioactivity. Marie Curie’s relentless resolve and insatiable curiosity made her an icon in the world of modern science. WebA clever technique was her key to success. About 15 years earlier, Pierre and his older brother, Jacques, had invented a new kind of electrometer, a device for measuring extremely low electrical currents. Marie now put the Curie electrometer to use in measuring the faint currents that can pass through air that has been bombarded with uranium rays. WebIn July 1898, P. Curie and Mme. Curie published the discovery of polonium, the element accompanying bismuth; in Dec. 1898, P. Curie, Mme. Curie and G. Bémont published … flink transactional.id
