Microwave oven safety

We use microwave ovens daily. It is necessary to have knowledge regarding microwave oven safety. We know that this microwave energy is different type of energy. There are microwave radiations associated with these microwave ovens. What is this microwave radiation? Is it hazardous to our health? The fact is that these microwaves are form of electromagnetic radiations. These microwave radiations have both electric and magnetic energy associated with it. The radio frequencies are low power electromagnetic waves. The x-rays that we use in health industry are powerful electromagnetic waves. These microwave waves are in between these two extreme ends.
It is to be made clear that microwaves are not x-rays. There can not be any harm to your health if there is some leakage of this microwave radiation. These microwave radiations are absorbed by food items and they pass through plastic, glass and paper. But most importantly, they are reflected back from metal surfaces. The absorption of microwave radiations does not contaminate food products. The food items do not become" radioactive" due to absorption of microwave radiations. The food cooked by microwave radiations is completely safe. If canned food is used, then it is possible that already present bacteria in canned food items may not get destroyed due to microwave radiations when this food is cooked.
There is no leakage of microwave radiations from microwave ovens. There can be very small microwave radiation possible which is not hazardous for human health. The government has made it compulsory for the manufacturer to give safety manuals along with these microwave oven products. There can be some health hazards in using microwave ovens. If you use water for heating, there can be what is called as super heating of water. In case of super heated water, a small disturbance or slight movement like picking up cup can give violent eruption with boiling water. Take all safety precautions to avoid any violent eruption reaction of superheated water.
It is necessary not to operate this microwave oven in empty condition. This can make lot of damage to magnetron and can cause serious safety problems. There are two sections in any microwave ovens. The first one is circuitry part. In this control section there are different types of fuses for the safety purposes. It is possible that your microwave oven might get over heated. There are safety thermal fuses to keep your microwave oven safe from over heating hazard. There are electrical fuses for many different controls. Both types of fuses are there for your and microwave oven's safety. It is necessary to clean your microwave oven regularly. If some debris is remaining inside your microwave oven it can cause unexpected problems. Follow the safety instructions given by the manufacturers seriously.
