Document Summary
Our planet is connected with the sun with more than just light, it also connects by the stream of charged particles that come from the sun other sources of radiation are galactic radiation (out of solar system) Tiny particles that make up everything in the world. Made of: positively charged protons, and neutrons which don t have a charge, negatively charged electrons, neutrons and protons are also called nucleons, since they form the nucleus. A is the atomic mass number, or the total number of nucleons (neutrons + protons) The carbon has 6 protons and 8 neutrons, therefore its called carbon-14. Radiation describes waves or particles that are emitted from unstable atoms. Radiation has been in the universe since the beginning of time. Radiation that surrounds us everyday is called background radiation. This includes radiation from sun, soil, water and cosic radiation. Two categories of radiation: non-ionizing and ionizing. Ionizing radiation has enough energy to break molecular bonds, creating ions.
