Effects on human body.
When the human body is close to the microwave radiation source (such as the working microwave oven), it can complain of dizziness, sleep disorder, memory loss, bradycardia, blood pressure drop and so on due to excessive radiation energy. It was found that when the human eyes were about 30cm near the leakage point of the microwave oven and the microwave leakage reached 1mW/cm2, they suddenly felt dizzy, and the fundus examination showed a little bleeding above the macula of retina.
The heating cavity of the microwave oven is made of metal, so the microwave can't penetrate. The oven door glass of microwave oven is made of a special material. Generally, safety protection measures such as metal protective net, oxygen carrier rubber, oven door sealing system and door lock system are designed to prevent microwave leakage. The most vulnerable part of the human body is the lens of the eye. If the eyes are exposed to microwave radiation that exceeds the safety regulations for a long time, their eyesight will decline and even cause cataracts. In order to protect users' health, the International Electrotechnical Commission and relevant departments of our country stipulate that the leakage of microwave at 5 cm outside the microwave oven door should not exceed 5 MW/cm2.
