EVS 1501 Lecture Notes - Lecture 6: Microwave Oven, Plywood, Boiling Point
Document Summary
Not enough energy to displace electrons from the atoms. This radiation does cause harm, but that harm is not obvious. It is a subject of debate and research. We will look at some case studies about it. It"s hard to generalize things about nonionized radiation, because there isn"t enough evidence, but we can look at each case independently. Microwave radiation: widely used that even we don"t know of. For example, if you are driving fast, and police stops you, microwave radiation is to blame. To dry and cure plywood (if plywood is damaged during processing, microwave radiation is used to find where is it damaged). To raise bread and doughnuts (used in companies, but not much at homes). Microwave oven radiation: microwave radiation is electromagnetic radiation. Radiation from the sun is also an electromagnetic radiation. Microwave radiation is used for cooking because it is easily absorbed by foods. As soon as this radiation enters food, it gets transferred into heat.
