PPT-1.3 Nuclear Decay and Radiation

Knowledge of subatomic particles has led to many advancements unfortunately besides the advancements in power plants there has been costsnuclear warfare and waste Nuclear Decay The nucleuscluster of protons and neutronsis in the centre of an atom. 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. You will learn about the various types of radiation and their effects..
