shaft of light is efficiency that comes from a source and travels through several(prenominal) material or through space. Light, heat and sound nuclear number 18 types of beam of light. The kind of ray of light discussed in this presentation is c everyed ionizing radiation because it tolerate produce charged particles (ions) in matter. Ionizing radiation is produced by seismal atoms. Un perpetual atoms differ from stable atoms because they have an excess of energy or potty or both. Unstable atoms argon say to be hot. In instal to reach stability, these atoms give off, or emit, the excess energy or mass. These emissions are called radiation. The kinds of radiation are electromagnetic (like light) and particulate matter (i.e., mass given off with the energy of motion). Gamma radiation and X-rays are examples of electromagnetic radiation. Beta and alpha radiation are examples of particulate radiation. Ionizing radiation hobo withal be produced by devices such as X -ray machines. Â Radiation exposure occurs by diagnostic X-ray. Irradiation by machine-generated radiation occurs only when the machine is saturnine on. > Â There is also vivid background radiation exposure. It comes from cosmic rays and from naturally occurring radioactive materials contained in the earth and in existent things. Irradiation Irradiation is exposure to dandy radiation.
Irradiation occurs when all or part of the body is undecided to radiation from an unprotected source. External irradiation does not delineate a somebody radioactive. Radioactive Contamination Contamination occurs when material that contains radioactive atoms is ! deposited on skin, clothing, or any place where is it not desired. If is master(prenominal) to remember that radiation does not spread or establish on or in people; rather it is radioactive contamination that can spread. A person contaminated with radioactive materials will be irradiated until the source of radiation (the radioactive material) is removed. A person is externally contaminated if radioactive material is on...If you regard to get a full essay, order it on our website:
