Will the signal jammer in the examination room cause harm to the human body?

According to the data of previous years, when the college entrance examination begins in July next year, the test room signal jammer equipped with electromagnetic signal blocking equipment will be assembled in many exams by the testing supervision agencies in various regions of my country as a way to prevent college entrance examination candidates from cheating. field. However, a post "The founder of the test room signal jammer said that the test room signal jammer is harmful to people" was generally intercepted by the media.

Regarding this news, the National Department of Education recently issued a statement. This situation lacks scientific and reasonable evidence and requires rigorous investigation by relevant departments to obtain evidence. The Tsinghua professionals who posted this view on social media are not Tsinghua University employees. The Department of Education also deliberately stated that although the Ministry of Education has no strict requirements on whether to use the test room signal jammer in the examination room, the test room signal jammer is currently a very effective method for cheating. According to the safety regulations of signal jammers in the examination room, a specific guidance method on the use of this equipment will be promulgated recently.

So the question is, will the signal jammer in the examination room cause harm to the human body?

Examination room signal jammer radiation source mobile phone similar

The relevant person in charge of the Student Department of the Education Department stated that the signal jammers in the examination room are 3 times harmful to the human body.

Will there be any adverse effects? You can’t vaguely say that there is harm or no harm. The radiation source is related to the distance. If it is far away, it will not cause much harm, but if it is close to the ear, it will cause great harm.

Regarding some problems with the signal jammer in the examination room, the reporter also visited Chengdu Basansiyi Information Technology Co., Ltd., which has been developing and selling signal jammers in the examination room for more than ten years.

"The harm caused by the signal jammer in the examination room is the same as that of a mobile phone. I don't have such a big reaction when I touch this thing every day." Chengdu Basansiyi Information Technology Co., Ltd., which manufactures the signal jammer for the dealer's examination room, responded to the reporter the question raised.

Because he has been developing and selling such new products, he has a certain understanding of the working principle of the signal jammer in the examination room. He said: "The electronic output power value of the mobile phone we use today is 3 watts, and the signal jammer in the examination room is less efficient. At 3 watts, if it is really so big, who would dare to use a mobile phone?"

I heard: the signal jammers in the examination room at this stage are all similar, and their output power is similar to that of mobile phones, and my products were actively sent to the Ministry of Public Security Electronic Devices for inspection before publicity, and there was no abnormality .

In addition, 150 movie theaters in Beijing have introduced this kind of test room signal jammer, 80% of which have been installed and used, and there is no phenomenon of physical discomfort in the covered area.
