Should Putin Worry About Russia's Spate of Whistleblowing? 2011-02-20T05:55:00Z Curie, in her enthusiasm, named in honor of the land of her birth, polonium. Woman in Science With an Introductory Chapter on Woman's Long Struggle for Things of the Mind 2011-01-12T03:00:29.853Z But as a nonsmoker, I wonder just where else this polonium may lie. Readers Respond to "Flu Factories" and Other Articles 2011-04-22T12:45:02.053Z Formally, it is to mark the 100th anniversary of Marie Curie receiving the Nobel Prize in Chemistry, for her discovery of radium and polonium. Chemistry's understated majesty 2011-01-05T18:20:00.977Z In consequence, cigarettes still contain as much polonium today as they did half a century ago. Radioactive Smoke: A Dangerous Isotope Lurks in Cigarettes (preview) 2011-01-05T13:15:00.257Z “When they prepared this, they never expected polonium would be known as a murder weapon,” she said. Leaked Cables Shed New Light on Ex-K.G.B. Officer?s Death in London 2010-12-20T23:09:02Z This statement is well illustrated by the delicate experiments that were required to isolate such rare elements as radium, polonium, helium and neon, which occur only in infinitesimal quantities. Woman in Science With an Introductory Chapter on Woman's Long Struggle for Things of the Mind 2011-01-12T03:00:29.853Z Unlike a missile flying through the air, or even polonium-210, the evidential trail of a cyber attack is difficult, if not impossible, to establish. Cyber warfare: Low blows 2010-10-13T23:05:00Z The fierce critic of former Russian President Vladimir Putin was poisoned with polonium in London in 2006. Berezovsky wins poison libel case 2010-03-10T13:06:00Z Alexander Litvinenko, a renegade Russian security officer living in London, was killed by poisoning with polonium, a rare radioactive substance, in 2006. Assassinations and technology: Hitmen old and new 2010-02-18T10:42:00Z Curie gave the name of polonium for Poland, her native land. A Brief Account of Radio-activity As Scott threw open the cargo doors and dropped to the rocky ground, he saw the crewmen checking blasters and the slender polonium tubes that could permanently blind a man. Feline Red It is well known that Pierre and Marie Curie used this new-found radioactivity to identify the new elements polonium and radium. A Brief History of Element Discovery, Synthesis, and Analysis The little instrument used a principle dating back to the early history of atomic energy, when scientists were exploring the nature of the strange force the Curies had discovered in radium and polonium. The Blue Ghost Mystery Her first discovery was that of the substance polonium—so named by Madame Curie after her native country, Poland. A History of Science, Volume 5(of 5) Aspects Of Recent Science In one ton of pitchblende about 0.2 gram of radium is present; this is about 5000 times greater than the amount of polonium present. A Brief Account of Radio-activity Curie has done such wonderful work in chemistry, that the Academy of Paris has long debated whether she should not be made an academician for her discoveries in connection with polonium and radium. How Girls Can Help Their Country All these material designs are more or less radio-active—namely, changing into other elements, but some, like radium, polonium, &c., are active to an extraordinary extent. Science and the Infinite or Through a Window in the Blank Wall Curie's discovery of polonium and radium—Their characteristics—Debierne discovers actinium. The New Physics and Its Evolution The substances uranium, thorium, polonium, radium, and their compounds are radioactive, radium being by far the most active. A History of Science, Volume 5(of 5) Aspects Of Recent Science Further, it became clear from the investigation of uranium minerals that radium, polonium, actinium, and ionium originated from uranium. A Brief Account of Radio-activity This is true also of the two other elements found in the ores of uranium and thorium, viz., polonium and actinium. Marvels of Modern Science The liquefaction of oxygen; the existence of radium, of helium, of polonium, of argon; the different powers of Roentgen and Cathode and Bequerel rays. The Jewel of Seven Stars Two other bodies, polonium and actinium, the one characterised by the special nature of the radiations it emits and the other by a particular spectrum, seem likewise to exist in pitchblende. The New Physics and Its Evolution In some cases the chemical action was determined and these new bodies were found analogous to well-known elements, as radium to barium, polonium to bismuth.
