Radioactivity

rThe Discovery of Radioactivity: The Dawn of the Nuclear Age Antoine Henri Becquerel was a French physicist who one day was photographing his wifes go along bring out the photograph of her skeleton. His wifes strive had been placed in the path of x-rays which was created by beaming an negatron ray muscle spring onto a cathode tube. These rays capable of producing an image on a photographic plate, excited many scientists, including Becquerel. Becquerel chose to canalize out the battlefield of radiation therapy and on March of 1986, he made a remarkable discovery. Becquerel did an experiment that showed that uranium emitted radioactivity without an external source of energy such as the sun. Becquerel proved that the radiation therapy he had discovered could not be x-rays, because x-rays ar neutral and cannot be dented in the magnetic field, and the newborn radiation was bent by the magnetic field proving that the radiation must be charged and different then th an x-rays. in that respect are threesome Classes of radioactivity; negative, positive, and electrically neutral.

The term radioactivity was actually was accustomed by a women names peeress Curie, who with her husband began canvass the discovery of Becquerel. The curies extracted uranium from ore and to their surprise instal out that the left over(predicate) ore showed more activity than the pure uranium. They did this for other(a) four or so years. The curies discovered two more elements, which are at present known as polonium and radium. Eventually the Curies died in outcome of being exposed in like m anner radioactivity. Radioactivity is a ind! welling bring out of our environment, and was a very important discovery purge though it was very dangerous and caused death to people. It is said that the news subject field Madam Curie wrote her conclusions on are still too radioactive too touch.If you want to get a slump essay, order it on our website: OrderCustomPaper.com
