Many merchants will consider many factors when installing anti-theft systems , such as installation distance, price of anti-theft systems, and detection sensitivity. Some people are also concerned about anti-theft systems for supermarkets, clothing stores, maternal and child store anti-theft devices, and other retail store anti-theft devices. Will there be a lot of radiation and will it be harmful to pregnant women?
Regarding the question "Do supermarket anti-theft systems emit radiation and are they harmful to pregnant women?", the answer is: supermarket anti-theft systems are not harmful to the body and pregnant women can pass with confidence!
Currently, there are three categories of EAS supermarket anti-theft devices: AM sonic and magnetic anti-theft devices, RF radio frequency anti-theft devices, and EM electromagnetic wave anti-theft devices. The working principle of the sonomagnetic anti-theft device is that resonance will occur when the oscillation frequency is the same, that is 58KHZ. When the product with the sonomagnetic label passes through the anti-theft device, resonance will occur, and the receiver will emit an alarm sound when receiving the alarm signal. Radio frequency anti-theft devices use radio waves to emit signals. When an object with a frequency of 8.2MHZ is detected, the anti-theft device will sound an alarm! The EM electromagnetic wave anti-theft system emits electromagnetic wave signals. Most of the high-end electromagnetic wave anti-theft devices on the market are controlled by software, and the frequency of radiation is also extremely small.
The unit of the industrial frequency band is μT, which tests industrial frequency electromagnetic waves below 50 Hz, such as home appliances and high-voltage lines; if the radiation is above 0.4μT, it is a strong radiation, and if the radiation is between 0.3 and 0.4μT, it is a warning value. As for 0.3μT Especially below 0.1μT, it can be considered safe. The unit of radio frequency electromagnetic waves is μW/㎝2. For example, the base stations of microwave ovens, mobile phones, and radio and television generally measure a frequency band of several hundred to thousands of hertz. Above 10 μW/㎝2, it will cause harm to the human body. During the working process of the anti-theft alarm, it does not produce any poisonous gas, high-voltage current or other conditions that are harmful to the human body. This cannot be compared with X-rays and MRIs in hospitals. The anti-theft alarm is a very small working process, and the process is harmful to the body. There is no harm.
