| The becquerel is a unit of radioactivity and corresponds to one radioactive disintegration per second. |
|
| The new a safety limit for plutonium in food will be one becquerel per kilogram. |
|
| One becquerel means the disintegration of one nucleus per second. |
|
| Becquerel in Paris wondered whether naturally fluorescent or phosphorescent substances might also emit X-rays. |
|
| This year is the centennial of the Nobel Prize in Physics shared by Henri Becquerel and the Curies for their pioneering work on radioactivity. |
|
| I've named it after Henri Becquerel in honour of the plant's peculiar beard. |
|
| Thus, thought Becquerel, he had extended his discovery of long-lived phosphorescence to metals. |
|
| The Curies resolved to learn as much as they could about the source of radioactivity in pitchblende, the ore with which Becquerel originally worked. |
|
| Along with her husband and Becquerel, Curie was awarded in 1903 the Nobel Prize in physics for research into radioactivity. |
|
| The Curies began researching radioactive elements after Henri Becquerel discovered, by chance, radioactive uranium. |
|
| Radioactivity was discovered in 1896 by the French scientist Henri Becquerel, while working with phosphorescent materials. |
|
| Details of the 1903 Nobel Prize in physics awarded to Antoine Henri Becquerel, Pierre Curie, and Marie Curie. |
|
| Girodet's wash drawings inspired by Ossianic themes reappeared in 1971 when the Musee de Montargis acquired eight of them from the artist's heirs, the Becquerel family. |
