...tiny laboratory in the Latin Quarter in Paris, working from ten to 20 hr. a day with uranium oxide to find out more about that queer radioactive family which begins with uranium and ends as lead. Since she knows most about radium she is now studying uranium and polonium, which she discovered in 1898 and named for her native Poland...
...hearts beat in vitro half an hour or so, then ceased. Professor Zwaardemaker added small amounts of potassium salt to his solution. The hearts began to beat again. They continued so for 24 hours. Potassium is weakly radioactive. Other radioactive elements gave the same stimulating results-radium, thorium, uranium, polonium...
...atomic disintegration, uranium (238.2) goes to ionium (230) to radium (226) to radon (222) to polonium (210) to lead...
...British House of Commons made an astounding insinuation last week-that the private Belgian concern, Union Miniere du Haut Katanga, which manufactures 90% of the world's radium under Belgian Government control, was restricting that valuable metal's production. The Belgian pitchblende mines, whence the related radium, polonium and lead are refined, are at Katanga, Belgian Congo. Those mines have far outdistanced the Jackinov mines in Czechoslovakia where Becquerel and the Curies got their first pitchblende supplies. Other, but at present little used, sources of radium are autunite deposits in Portugal, betafite deposits in Madagascar, carnotite deposits...
...common at the Sorbonne, but this particular one had elaborated upon an important discovery made by her mother. It was Mlle. Irene Curie, of Paris, continuing the radiological research of her mother, Mme. Curie, joint discoverer of radium. Mlle. Irene's thesis was on the alpha rays of polonium...
