Foldable Notes. Alpha Particles. 1. An . alpha particle . is a positively charged particle made up of two protons and two neutrons—the same as a helium nucleus.. 2. The . common symbol for an alpha particle is .
Radioactivity. Science Park HS -- Honors Chemistry. Early Pioneers in Radioactivity. Roentgen:. Discoverer of X-rays 1895. Becquerel:. Discoverer of Radioactivity 1896. The Curies:. Discoverers of Radium and Polonium 1900-1908.
True. False. Types of radioactive decay. Gamma. Beta (+,-, . e.c. .). Alpha. Neutron emission. Fission. Fusion. http://ie.lbl.gov/education/isotopes.htm. Gamma Decay. Nucleus in excited state gives off energy as a photon.
Continued. Minimising Exposure. As any exposure to ionising radiation could potentially damage cells and lead to cancer, . w. hen handling radioactive materials and in situations where workers are exposed to ionising radiation the ALARA principle should be employed..
Pierre Curie was already a famous scientist before he married Marie Sklodowska in 1895. This famous couple did not only find true love, they also discovered radium and polonium. For their groundbreaking research in radioactivity, the couple were awarded the 1903 Nobel Prize in physics. It was Marie Curie who coined the term "radioactivity", and in her honor, the 1910 Radiology Congress chose the curie as the basic unit of radioactivity. Pierre died from being run over by a horse drawn wagon, but Marie continued their research, and was eventually awarded a second Nobel Prize, the 1911 prize for Chemistry. She died in 1934, suffering from pernicious anemia which had undoubtedly been the result of years of radiation exposure..
Learning Objectives. I must be able to recall when ionising radiation is emitted. . I should be able to describe the three types of ionising radiation.. I might be able to explain the dangers of ionising radiation..
The Discovery of Radioactivity. Henri Becquerel (1896): . Investigated the effect . of sunlight on crystals of . uranium salts. . By chance he left sample . . resting on a . photographic plate wrapped .
