How much radiation does the microwave oven have?
According to the national security regulations, the microwave radiation protection of microwave ovens should be controlled within a certain range. In the family life environment, the microwave radiation power density of the microwave oven should not exceed 40μW, because the safe electric field strength that the human body can usually bear should not exceed 20 V/m. ..
The microwave oven works according to the internal thermal effect. The internal thermal effect can quickly heat the water molecules in the cooked food by vibration heating in a short time. During the cooking process, the microwave oven will generate strong electromagnetic waves. Usually, microwave ovens can't completely leak electromagnetic waves, but they can be controlled within the range of safety standards.
At different distances, the microwave radiation produced by microwave ovens to human body is different. We can use the electromagnetic radiation tester to determine the specific value. Bian Xiao detected the radiation values from the top, side, back and front in turn, and got the following results: the radiation values from the side of microwave oven are the smallest, followed by the back, and the radiation values from the top and front are the largest.
The farther away from the microwave oven, the less electromagnetic radiation we receive. When the distance reaches more than 70 cm, the electromagnetic radiation received by the human body can be ignored.
According to the working principle of microwave oven, we can be sure that electromagnetic radiation will only leak around the door, and the value of microwave radiation will gradually decrease with the increase of distance. Therefore, when we stand one meter away from the microwave oven, we will not be affected by the radiation of the induction cooker. Usually, the radiation of microwave ovens is mainly affected by three factors: radiation intensity, radiation time and radiation distance.
Electromagnetic radiation is harmful to human body for many years, which will affect children's intelligence, vision and bone development. , and can cause cardiovascular diseases, reproductive system diseases, immune system diseases, etc. We must pay attention to prevention.
Finally, Tuba Rabbit Bian Xiao reminds everyone that the microwave oven is convenient and practical, and it is the most ideal cooking tool for urbanites in their busy lives. However, the electromagnetic radiation emitted by microwave ovens is several times that of other household appliances. When working in the microwave oven, we'd better keep a certain distance, so as to avoid the radiation generated when cooking food affecting our health.
