It is the radiation generated by sun that . regulates the temperature of earth. . . CLASSIFICATION OF RADIATION: ionizing or non-ionizing types. . Radiation.  is a process in which energetic particles or energetic waves travel through vacuum or media. .. Radiobiology.  (also known as radiation biology) is the study of the action of ionizing radiation on living things.. INTRODUCTION . Radiation is energy that moves through space or matter at a very high speed. This energy can be in the form of . particles. , e.g. alpha or beta particles, which are emitted from radioactive materials, or .
