PPT-Why is the sky blue? Radiation

Radiation is the direct transfer of energy by electromagnetic waves Infrared radiation has wavelengths that are longer than wavelengths for red light the red of ROY G BIV Not visible but can be felt as heat. 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 00 Grilled Chicken Bacon Tuna Salad Chicken Salad Smoked Salmon CHOCOLATE CHIP wo nuts CHOCOLATE DECADENCE PEANUT BUTTER OATMEAL RAISIN CHOCOLATE CHIP w nuts MONTHLY SPECIAL BAKED LAYS ORIGINAL CLASSIC LAYS BAKED CHEETOS NACHO CHEESE DORITOS SUNCHIPS .

Radiation refers to the process that is concerned with the passage of energy between places through space. . It is the radiation generated by sun that . regulates the temperature of earth. . . CLASSIFICATION OF RADIATION: ionizing or non-ionizing types. . GUIDE Activity The rate of disintegration per unit time is measured in curies and based on the following standard: Unit Quantity 1 curie (Ci) 3.7 X 10 10 dps (disintegrations per second) 1 millicuri The cell life cycle The cell cycle G0 = Cell is resting G1 = RNA and proteins are made S = DNA is made G2 = Apparatus for mitosis is built M = Mitosis (the cell divides into 2 cells) G0 phase (restin . Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . •. Radiation biology . is the study of the action of ionizing radiation on living organisms . •The action is very complex, involving physics, chemistry, and biology . –Different types of ionizing radiation .
