Microwave ovens are an extremely convenient kitchen appliance and are almost indispensable in every family when they have many uses such as heating food, baking, steaming... However, in the process of using some people who have suffered burns, or other injuries from microwave radiation. So how to use the microwave properly?1. What parts does the microwave include?
The first thing you need to know is that microwaves usually produce a type of electromagnetic radiation. These waves cause the water molecules in the food to vibrate. These vibrations create heat that cooks the food.The waves are generated by a vacuum tube in the furnace called a magnetron. They are reflected in the metal interior of the oven, can pass through glass, paper, plastic, and similar materials and be absorbed by food.
Microwaves are a type of non-ionizing radiation. They do not have the same risks as X-rays or other types of ionizing radiation. (Ionizing radiation is a more energetic type of radiation that can cause changes to human cells.)
2. Risk of injury when using a microwave oven
Most microwave-related injuries are the result of burns from heat from hot containers, overheated food, or exploding liquids. Very rare cases of injury related to microwave radiation.In the case of common trauma these radiation injuries are caused by exposure to large amounts of microwave radiation that leak through openings, such as those in microwave cushions. However, the manufacturer's regulations require that the microwave oven be designed to prevent high-level radiation leakage. Therefore, manufacturers must certify that their microwave ovens comply with specific safety standards. These standards require that any radiation emitted by the furnace be much lower than what is known to cause injury.
Although some are concerned that microwave ovens may interfere with some electronic pacemakers, today's pacemakers are designed to counteract this interference.

3. 5 tips to use the microwave properly
3.1. Follow the manufacturer's instructions for use The instructions in the user manual provide recommended operating procedures and safety precautions. For example, you should not use some microwave ovens when they are empty. In addition, you should not heat water or liquids for longer than the manufacturer's instructions and recommendations.3.2. Use microwave-safe containers Use cookware that is specifically designed for use in the microwave. In general, you shouldn't use metal or aluminum foil pans because the microwaves reflect them back, causing food to cook unevenly and possibly damaging the oven. You also shouldn't use some plastic containers, as heating food can cause the plastic to melt. The manufacturer recommends using glass, ceramic, and plastic containers labeled for use in the microwave oven.

3.4. Leak Test There is no reason to be concerned about excess microwave radiation leaking from these ovens unless the door hinges, latches or washers are damaged. The manufacturer recommends taking a close look at your oven for any of these issues. The agency also recommends that you do not use the oven if the door is not securely closed or is bent, warped or damaged.
3.5. Do not use the oven with the door open Experts monitor electronic devices for radiation safety and have received more and more reports of microwave ovens appearing to stay on and operate when the door is open. . They recommend that you immediately stop using the microwave oven if this happens.
