Microwave radiation from cell phone jammer can harm the human body
China Broadcasting Network, Beijing, May 27, news. The microwave radiation of cell phone jammer can harm the human body. The inventor strongly opposes its use in the examination room. "I didn't expect that the mobile phone shielding device would be used in the examination room!" Tang Tai, the chief engineer of the Soft Media Security Technology Laboratory of Tsinghua University, told the reporter of the Morning News yesterday afternoon. "The microwave radiation of mobile cell phone jammer affects parts of the human body, especially the brain. Harmful, it will seriously affect candidates' logical thinking and on-the-spot performance." In 1999, Tang Tai led a technical team in the laboratory to successfully develop the first mobile jammer in China.
In recent years, Henan Zhenping and Puyang have repeatedly reported fraud cases in college entrance examinations. Similar incidents have also been reported in Bozhou, Anhui. Cheating in English Band 4 and 6 in a college in Xi'an, and cheating in Shenyang, Liaoning, are all related to mobile phones without exception. Since the Hubei Examinations Institute installed nearly 200 mobile phone communication jammers in its standardized examination room to deal with the many "illegitimate" mobile phones in the CET-4 and CET-6 exams, Beijing, Shandong, Shanxi, Northeast and other places have followed suit. .
The development of jammers is mainly to protect the safety of gas stations and oil depots. Tang Tai explained that the cell phone jammer were basically developed for use by special departments such as troops and security, mainly to protect gas stations, oil depots, communication hubs and other places. Safety. However, unexpectedly, the mobile phone jammer he developed and invented is widely used in the private sector.
"About 1999, cell phone jammer spread to the people very accidentally." Talking about the proliferation of mobile phone shielding devices, Tang Tai showed helplessness in his words. He said that there were gas station explosion accidents in Henan and Guangxi at that time. As a member of the accident investigation expert team, Tang Tai came to the conclusion that the use of mobile phones caused the explosion, and suggested that gas stations use cell phone jammer to avoid violent changes in microwave pulses. explosion. "As a result, the instrument was imitated by many manufacturers, and then developed to the point where it is almost out of control today." Tang Tai said. What was even more unexpected was that the products developed at the beginning were also welcomed by examination management organizations in various places. It is reported that following the installation in some test centers in Shandong, Heilongjiang, Liaoning and other provinces and cities last year, the admissions offices of Gansu, Nanjing, Jiangsu and other provinces and cities are also preparing to use it this year.
