PPT-Types of Nuclear Radiation

Foldable Notes Alpha Particles 1 An alpha particle is a positively charged particle made up of two protons and two neutronsthe same as a helium nucleus 2 The common symbol for an alpha particle is . The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform Chapter 25. Marie Curie was a Polish scientist whose research led to many discoveries about radiation and radioactive elements. In 1934 she died from leukemia caused by her long-term exposure to radiation.
