Rep. Peter A. DeFazio (D-OR), House Transportation and Infrastructure Committee chairman, inquired about the federal government’s research into the potential health effects of RF radiation and the FCC’s guidelines for safe human RF exposure levels, in light of 5G rollout, in a letter last week to FCC Chairman Ajit Pai and the Food and Drug Administration’s acting commissioner, Norman Sharpless.
“As you know, the impending rollout of 5G technology will require the installation of hundreds of thousands of small cell sites in neighborhoods and communities around the country and these installations will emit higher-frequency radio waves than previous generations of cellular technology,” DeFazio wrote. “This means Americans will be exposed to more non-ionizing RF radiation than ever before.”
The FCC’s current RF-safety guidelines were set in 1996, DeFazio noted, and in 2012 the Government Accountability Office recommended that it should “formally reassess and, if appropriate, change its current RF energy exposure limits.” The commission has taken no action in this area.
Meanwhile, DeFazio notes the growing anxiety about RF among the public in general and in his district in particular. “States and municipalities across the country are hearing from citizens who are concerned about this technology being installed in their communities,” he wrote.
Alex Gellman, CEO and co-founder of Vertical Bridge, told AGL eDigest that there is no science-backed evidence behind the link between cell towers and health issues. The objections voiced at zoning meetings are based on emotion and misleading information downloaded from the internet, he said.
“As an industry, we should use science to counter that emotion,” Gellman said. “The facts are on our side, but that doesn’t work unless we use them. We need to use data to make our case about the safety of cell towers. The exposure from a cell tower is measured in the power output of lightbulbs. With the rising tide of conversation on this subject, we should pull out the facts.”
Allan Tantillo, vice president of new technologies at Vertical Bridge, said the deployment of large numbers of small cells has stirred up emotions surrounding the health and safety of cell towers. “We are rolling out a new technology where people are hearing about hundreds of thousands of new cell sites,” he said. “People have a hard time conceptualizing and understanding the deployment of 100,000 small cells that are 1,000 feet from them. They just hear numbers and think ‘I was kind of worried about cell towers but now they are really going flood us with even more radio waves. There’s got to be a problem.’”
The science and physics involved haven’t changed, according to Tantillo. “The small cell sites produce lower power output that previous cell tower buildouts,” he said. “The power output of a small cell on a light pole is relatively the same as what you get from many devices that you have in your home already.”
Tantillo said the wireless infrastructure industry and cellular carriers need to join together to address the health concerns. He said that when he was with T-Mobile, he was the driver behind the development of a website, www.howmobileworks.com, which educated municipalities on a number of issues relative to cell tower development. It offers conclusions based on facts about health concerns from a number of sources. Here are a few:
Gellman said individual companies should not have to go it alone in the educational process. Both the cellular companies and the infrastructure companies should align on a set of information and share that information. “The science is on our side; we just need to be good at educating,” he said.
Tantillo stressed that the industry needs to be proactive with its message and take the right tone that is conscious of people’s emotions. “We need to be prepared to provide the right set of facts to those that are making the decisions to balance out the emotional appeals,” he said. “The law doesn’t allow city officials to take health and safety into account in tower zoning hearings, but you can’t legislate emotion.”
DeFazio, however, is looking for more than just general references to scientific literature, such as the ones above. He is asking the FCC for the specific health-related studies, what gaps remain in our knowledge of the possible health effects of 5G, and the steps it has taken to educate the public about the RF radiation and safety relative to 5G technology. He seems to believe that 5G technology somehow changes the health effects of RF radiation.
“It is clear that the federal government has not been transparent enough about the current status of 5G RF radiation research and its guidelines on RF exposure limits,” he wrote. “The FCC’s and FDA’s responses to congressional inquiries on this issue have been less than satisfactory, merely reiterating general statements that 5G technology is safe without citing specific research or studies.”
Far above any band used for radio communications, alpha, beta, neutron and gamma rays and x-rays are known as ionizing radiation, which means they can damage living tissue, causing radiation burns and cancer. It is possible that the public confuses this type of radiation with radio waves from the AM band up to the millimeter-wave band, which are non-ionizing. They can only hurt you by heating up the tissue of your body. It should be noted that the FCC’s regulations set the limits to public RF exposure at 50 times below any level that is deemed to be harmful.
