Is it reliable that radio frequency jammers are harmful to human body?

  • 2022-06-24
Continuing from last year, this year, RF jammers with signal jamming function were installed in many examination halls by local examination management organizations as a technical means to prevent college entrance examination candidates from cheating. However, an article titled "the founder of radio frequency jammers claimed that jammers are harmful to people" was widely reprinted by the media.

In this regard, the Ministry of Education officially stated yesterday that there was no scientific evidence for this statement. After their investigation, Tsinghua experts who made this statement in the media were not employees of Tsinghua University. The Ministry of education also said that although the Ministry of education has no mandatory requirements on whether to use radio-frequency jammers in examination halls, radio-frequency jammers are the best means to effectively prevent large-scale cheating at present. Previously, a requirement on the safety of using radio-frequency jammers in schools has been issued, and a guiding method on using the instrument will be issued in the near future.

Is it reliable that radio frequency jammers are harmful to human body?

The radiation of RF jammer is similar to that of mobile phone

The person in charge of the student Department of the Ministry of Education said that the harm of radio-frequency interference instrument to human body cannot be generally said to be harmful and harmless. Radiation is related to distance. If it is far away, the impact is very small, and if it is close to the ear, it will have a great impact.

With regard to some problems of RF jammers, the reporter also interviewed Nanjing Bokang Electromechanical Technology Co., Ltd., which has developed and sold RF jammers for more than ten years.

"The damage caused by the radio frequency interference instrument is the same as that caused by the mobile phone. I don't have that big reaction when I touch this thing every day." Nanjing Bokang Electromechanical Technology Co., Ltd., which produces and distributes RF jammers, answered the questions raised by the reporter.

As he has been developing and selling such products, he has a certain understanding of the working principle of the RF jammer. He said: "the electronic power value of the mobile phone we use now is 2 watts, while the power of the RF jammer is less than 2 watts. If there is such a big response, who dares to use the mobile phone?"

It is said that the current RF jammers are almost the same, and their power is almost the same as that of mobile phones. Moreover, our products were sent to the No. 1 Electronics Institute of the Ministry of public security for testing before promotion, and no abnormality was found.
