Does the radiation from the supermarket anti-theft alarm system affect pregnant women? [Bohang China]

 

In daily life, when you enter and leave the supermarket, you may find that there are various burglar alarms at the door. The supermarket anti-theft alarm system can prevent theft of supermarket goods and reduce security risks. Recently, a small editor has been seen on a forum. The article "The radiation of the anti-theft device will affect pregnant women" is attracted. I believe that everyone will doubt this question when they see it. Is it true or false? Bhang China got the real answer after communicating with the technicians and checking the corresponding materials online.

First of all, we will analyze the safety value of electromagnetic radiation frequency. The safety standards that have no effect on the human body are: high frequency radiation is less than 10 μW/cm2, low frequency radiation is less than 10 V/m; the middle zone can have harmful effects on the human body: The high frequency radiation is less than 40 μW/cm2 and the low frequency radiation is less than 25 V/m. The mainstream supermarket anti-theft system on the market is mainly radio frequency anti-theft system, acoustic magnetic anti-theft system and electromagnetic anti-theft system. The detection frequency range of radio frequency anti-theft system is 7. x~8. x megahertz. 


The transmitted signal is a radio signal, which is the same signal as the mobile phone and the broadcast. Its radiation frequency complies with the safety standard; the acoustic magnetic anti-theft system is the most used on the market at present, and its detection rate is high, anti-interference is strong, and almost zero false positives are reported. It transmits and receives the resonance signal, the radiation frequency is also low and also meets the safety standard, and the electromagnetic wave anti-theft system transmits and receives the electromagnetic wave signal. The high-end electromagnetic wave anti-theft device on the market is mostly controlled by software, and the frequency of the radiation is extremely small.

The electrical appliances in our homes also have radiation, mainly magnetic radiation, and the frequency bands are divided into industrial frequency bands and radio frequency segments. The main frequency bands include TVs, computers, hair dryers, refrigerators, etc. 


The radio frequency segments mainly include mobile phones and microwave ovens. In the half-meter range of the front, the conventional CRT TV has a radiation value of 0.12 μT at the moment of normal power-on; the radiation value during normal viewing is 0.126 μT, and the radiation value within half a meter at startup can reach 2.4 μT. It can be said

Any live products have radiation, and supermarket anti-theft alarm systems are also available, but they are all tiny, and have no effect on the human body, so the truth is clear to the world, and supermarket anti-theft alarm systems have no effect on pregnant women.
