Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum. Alpha radiation consists of alpha-particles (α \alpha α), each of which contains two protons and two neutrons. This is the same as a helium nucleus. This is the same as a helium nucleus. Beta radiation consists of beta particles ( β \beta β ). gamma radiation: is a type of electromagnetic radiation, the same as visible light or radio waves, but much more energetic. It is a very penetrating type of radiation that is best shielded by large amounts of lead or concrete. When you have completed this course, you will be able to. Explain the development of the nuclear model of an atom. Use atomic notation to describe the structure of different atoms. A secondary school revision resource for AQA GCSE Additional Science about radiation, atoms, isotopes, nuclear fission and fusion Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in shells. The numbers of subatomic particles in an atom can be calculated from its atomic number and mass number. Background radiation is all around us all the time. (a) (i) Radon is a natural source of background radiation. Name another natural source of background radiation. Atoms, Radiation, and Radiation Protection offers professionals and advanced students a comprehensive coverage of the major concepts that underlie the origins and transport of ionizing radiation in matter.
