"The scientific evidence from in-depth examinations strongly demonstrates that wireless devices do not pose a public health safety hazard," said John Voss, vice president for public health affairs at CTIA-Wireless Alliance, the agency's An international organization representing the wireless communications industry. "Furthermore, there is currently no principle of action to prove that equipment that meets the electromagnetic radiation standards promulgated by the FCC will cause negative effects on human health." Including the U.S. Food and Drug Administration, the International Commission on Non-Ionizing Radiation Protection, the American Cancer Society and the World Health Organization This view is echoed by many major research institutions, including organizations. (The International Commission on Non-Ionizing Radiation Protection, however, believes that assessment of the health effects of wireless devices should continue as wireless technology becomes more widespread.) Voss also pointed out that statistics from cancer registries—more than those from the National Cancer Institute— A database from the Surveillance, Epidemiology and End Results program - also shows that there has been no increase in the incidence of brain cancer from the early 20th century to the present. In countries such as Denmark, Finland, Norway and Sweden, where mobile phone use was widespread earlier than the United States, brain cancer rates also remained stable from the 1970s to the early 2010s. If mobile phones are likely to cause brain cancer, then the incidence rate should increase accordingly. "If you look at all the biological and experimental studies," Voss said, "there's overwhelming evidence that there is no link between cell phones and health impairment." Segerbeck was An excellent telecommunications engineer. He worked for more than 20 years at Ellemtel, a subsidiary of Swedish telecommunications giant Ericsson, where he was responsible for leading an engineering team to design advanced integrated circuits used in communication system prototypes. When he worked, he always used the latest and most advanced computers and communications equipment at the time, many of which were only available to Ericsson and the Swedish military. But the long-term impact of this work is that his body is exposed to excessive non-ionizing radiation from computers, fluorescent lights and wireless communication antennas installed outside his windows. In the late 1980s, 10 years after he started working in telecommunications, he noticed the first symptoms - dizziness, nausea, headaches, burning sensations and red spots on his skin. Of the more than 20 members of his group, all but two reported the same symptoms, he said, but he was the one who reacted the most. His electromagnetic hypersensitivity continues to worsen, and he says that even radar from low-flying aircraft now affects his body. Segerbeck believes a combination of strong electromagnetic storms in his office and possibly noxious odors emanating from brand-new computers caused the situation. "But the company's doctors couldn't figure out what was going on," he said. Agni Frederiksson, who ran Segerbeck's group when he worked at Ellemtel and retired from Ericsson in 2006, said a frequently reported symptom was a "hot feeling in the face," but everyone attributed it to Because of the new computer workstation. When members of Segerbeck's team started calling in sick, and colleagues in other departments started reporting similar symptoms, Fredriksson recalls: "We just started to get serious about what might be causing these problems. After reporting the symptoms, In the most concentrated groups, panic was high.” The company opened a new workplace for its most affected employees, with about six or seven people in a fully shielded room. Others have switched to other computer workstations, and still others have been asked to reduce the amount of time they spend working in front of a computer screen. No one had ever encountered such a situation before. "What's so special about us?" Fredriksson recalled asking. Later he learned that other companies had encountered similar problems at that time, but this information was controlled within the company. Ericsson was a key member of the company's design team at the time, and Ericsson went to great lengths to keep him on the job.In the early 1990s, the company installed metal shielding around his bedroom and study room to protect him from radiation exposure while sleeping and working. In order to allow him to go out, the medical institution also provided Segerbeck with an anti-electromagnetic radiation suit, which is usually equipped for engineers who work very close to telecommunications towers and high-voltage power lines. The company even specially modified a Volvo sedan for him so that he could commute to get off work safely. But by the mid-1990s, when cell phone towers began to pop up across Stockholm, he stopped going to work and was forced to retreat into the mountains. In 1993, Ericsson published a report titled "Allergy in the Workplace," which focused on what happened in Segerbeck's lab. In the foreword, Ellemtel Vice President Al Young-6-1 Mattson and Executive Director Rodoby Johnson write: "A new problem has arisen in the work environment: allergies. In response to traditional occupational injuries The exception was allergies, when the first serious cases appeared in the late 1980s, and we were completely at a loss. We saw allergies as a serious threat to our business... We began to wonder if we were facing a penalty from the modernization process." A year later, Ericsson shut down Segerbeck and him. group working in laboratory. In 1999, the company fired Segerbeck. "He is no longer able to do the job we hired him to do," an Ericsson spokesman said. Segerbeck took the matter to a Swedish labor arbitration tribunal, but ultimately lost the case. He admitted he had no way of proving what caused the condition. "It's hard to know what exactly causes it and what its effects are," he said. "No one can say exactly what makes us sick." And it's impossible for him to find a doctor from a medical institution. an appropriate treatment method. Even a trip to the hospital, where electronic equipment could kill him, he said. Alrica Aberg, a doctor specializing in electromagnetic allergy, has been following Segerbeck from the earliest stages of his illness and has now treated more than 800 allergy patients. She said she found that symptoms ranged in severity, from the mildest symptoms of insomnia and dizziness, to the severe symptoms Segerbeck experienced. “There is always electrical activity going on in all the cells of the human body, so it’s not surprising that someone with electromagnetic hypersensitivity would have their entire body affected,” she says. For those patients who report milder symptoms, Aberg recommends that they remove all wireless electronic devices from their homes, including cell phones, cordless phones, wireless computer network equipment, etc. But people are still exposed to radiation from other people's wireless devices. There are hundreds of "refugees" with electromagnetic allergies in Sweden, she said. These people can only avoid the effects of electromagnetic fields by moving, and some people move more than once. She said one husband and wife with allergies lived in an RV so they could be moved quickly if their symptoms worsened. "The diagnosis of electromagnetic hypersensitivity is controversial, and many people don't know or don't care about it," Aberg said. "But many people (sufferers of electromagnetic hypersensitivity) feel that the place they live is unsafe. We should not Arbitrarily adding more electromagnetic fields regardless of people's reaction to them."
