PPT-Radiation There are 3 main types of nuclear radiation

Alpha Beta Gamma Alpha The unstable nucleus releases an alpha particle α which is 2 protons and 2 neutrons 4 He nucleus Happens usually with very BIG nuclei This process drops the atomic number down by 2. Most of them have the potential for both beneficial and harmful effects Even sunlight the most essential radiation of all can be harmful in excessive amounts Most public attention is given to the category of radiation known as ionizing radiation Thi 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. You will learn about the various types of radiation and their effects.. Knowledge of subatomic particles has led to many advancements- unfortunately besides the advancements in power plants there has been costs-nuclear warfare and waste. Nuclear Decay. The nucleus-cluster of protons and neutrons-is in the centre of an atom. Charles Perrow, Emeritus Professor, Yale University.
