| Rutherford was studying the structure of matter by bombarding a very thin gold foil with the alpha radiation from radium and polonium. |
|
| Gentry had discovered that granites contain microscopic coloration halos produced by the radioactive decay of primordial polonium. |
|
| This generator is a small pellet of polonium and beryllium, separated by foil within the fissionable fuel core. |
|
| Among the commonly known alpha emitters are various isotopes of polonium, radium, thorium, uranium and all of the transuranium elements. |
|
| Arsenic, formaldehyde, hydrogen cyanide, polonium and ammonia are among some of the 4,200 chemicals in a cigarette. |
|
| Once the polonium had been recognized, police were able to trace the source of the poison to the Millennium hotel in Mayfair. |
|
| But their tests were for gamma, not alpha, radiation, so they naturally would have missed any polonium diagnosis. |
|
| The three men went for a meal at the Itsu sushi bar in Piccadilly, where polonium was also detected. |
|
| Polonium is a reactive silvery-grey metal, and like its halogen neighbour, astatine, polonium does not have any stable isotopes. |
|
| Further research led her to the new elements radium and polonium, named after her native Poland. |
|
| In Lugovoi's room, 107, the highest reading came from the bathroom plughole, leading to the suspicion he may have thrown the polonium away. |
|
| They discovered polonium traces on the seats – 26E and 26F – where Kovtun and Luovoi had been sitting. |
|
| It has been reported that some microbes can methylate polonium by the action of methylcobalamin. |
|
| Due to alpha particle radiation, ingested polonium could cause irreversible damage to the kidneys, liver, and spleen. |
|
| The leachate was separated from the solids by centrifugation, and the dissolved polonium isotopes in the liquid were plated spontaneously onto a silver planchet. |
|
| That would be Nobel Prize winner Marie Curie, the gal who discovered radioactive polonium. |
|
| Mr Litvinenko's home in north London, where traces of alpha radiation from polonium 210 have been found, was still being examined yesterday. |
|
| Mr Litvinenko died from radiation poisoning after, it would seem, being slipped a potion containing an isotope of polonium. |
|
| The accuser also mentioned that Arafat had been poisoned with polonium. |
|
| Applications of polonium are limited due to its high radioactivity. |
|
|
|
| Large quantities of polonium, a highly radioactive substance from the Russian nuclear cities, are misappropriated, transported all over Europe, and no one knows how it can have happened. |
|
| Natural radionuclides in the Canadian North include polonium and lead. |
|
| Occasionally, polonium is applied on brushes to remove the dust present on photographic films, and it is a popular anti-static agent in textile mills. |
|
| He devised a simple apparatus that consisted of a cylinder containing a polonium source and beryllium target. |
|
| The items in the bag were examined by Switzerland's Institute for Radiation Physics, which found elevated traces of polonium. |
|
| Physics and chemistry are similarly going out of fashion in Britain, and who is to gainsay the value of knowing the laws of thermodynamics and the place of polonium in the periodic table? |
|
| Doctors thought Litvinenko had been given thallium and only found radioactive polonium 210 with their final test. |
|
| The 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 metalloids are adjacent to a diagonal line from boron to polonium. |
|
| The rare elements polonium and astatine are also sometimes included. |
|
| They are accused of trying to poison Litvinenko for the first time later that day – and of succeeding two weeks later when they slipped radioactive polonium into his tea. |
|
| Det Insp Craig Mascall of the Metropolitan police said forensic experts later found large quantities of polonium in both Lugovoi and Kovtun's hotel rooms. |
|
| The year 2011 marks the one hundredth anniversary of the Nobel Prize in Chemistry awarded to Maria Sklodowska-Curie, recognizing her discovery of the elements radium and polonium. |
|
| In Germany, Walther Bothe and his student Herbert Becker had used polonium to bombard beryllium with alpha particles, producing an unusual form of radiation. |
|
| How the polonium was delivered into Arafat's system remains a mystery. |
|
| Maybe it was leaking and polonium accumulated in his body gradually. |
|
| They emit penetrating gamma radiation that is much more of a hazard than the alpha or beta radiation from cesium, cobalt, strontium or polonium,' LaMastra said. |
|
| In 1911 Marie Curie was awarded the Nobel Prize in Chemistry for producing a pure metal sample of radium and establishing the atomic weight of radium and polonium. |
|
| Polonium is also at the center of a major plot line currently playing out on the daytime soap opera General Hospital. |
|
| Polonium 210 is a natural contaminant of tobacco, providing additional evidence for the link between smoking and bronchial cancer. |
