Arlington, TX – Studies have shown that environmental levels of RF energy routinely encountered by the general public are typically far below levels necessary to produce significant heating and increased body temperature. But, what if that’s not true in all cases?
What if there are situations, particularly in workplace environments near high-powered RF sources, where the recommended limits for safe exposure of human beings to RF energy could be exceeded? What ARE the restrictive measures or mitigation actions necessary to ensure the safe use of RF energy?
“The FCC is required by the National Environmental Policy Act of 1969 to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment,” explains Herman Torres, VP of Sales at Innovative Insulation, the leading manufacturer of radiant barrier insulation for the DIY residential market and professional installers. “But there are other organizations like the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers, Inc. (IEEE), and the National Council on Radiation Protection and Measurements (NCRP) that have issued recommendations for human exposure to RF electromagnetic fields. Sometimes, it’s tough to stay on top of what is really going on.”
Torres explains that his company’s product called RF Shielding Radiant Barrier is designed to be a reflective insulation keeping 99.9 percent of the electronically transmitted RF waves emitted from a variety of sources away from people. “Let’s face it,” he says. “Not knowing what radiation can do to you is not an excuse for not taking proper precautions.”
According to the FCC, the Commission adopted the NCRP’s recommended Maximum Permissible Exposure limits for field strength and power density for the transmitters operating at frequencies of 300 kHz to 100 GHz. In addition, they adopted the specific absorption rate (SAR) limits for devices operating within close proximity to the body as specified within the ANSI/IEEE C95.1-1992 guidelines.
“The FCC has a 38-page document called ‘Questions and Answers About the Biological Effects and Potential Hazards of Radio Frequency Electromagnetic Fields’ that people will find useful,” he says. According to Torres, the document covers everything from what Radio Frequency Energy is, how we use the energy, microwaves, which are a specific form of radio waves, and much more.
“But it was written in 1999,” he adds, “and that’s a while ago, isn’t it? So when the document says, ‘It has been known for many years that exposure to high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly,’ they are talking about microwave ovens and other sources. How many more sources of such radiation exist today than 20 years ago?”
Innovation Insulation’s RF Shielding Radiant Barrier insulation reflects 99.9 percent of the electronically transmitted Radio Frequency waves emitted from a variety of sources, from an inventory scanner tool to a “smart” utility meter. The company’s RF Shielding is a reflective insulation that is white on one side, silver on the other, and comes in either Super R® Plus Radiant Barrier or Tempshield® Reflective “Bubble” Insulation rolls. It is tested to IEEE-299 by a certified independent laboratory and tested for a frequency range of 10kHz to 10GHz, proving to be up to 99.06% effective in shielding signals.
RF is produced by both natural and artificial sources. Naturally, RF comes from the sun, the earth and the ionosphere. Artificially, RF radiation stems radio and television broadcasting, mobile phones, wireless networks such as Wi-Fi, cordless phones, police and fire department radios, point-to-point links and satellite communications. Other sources of RF fields include microwave ovens, radar, industrial heaters and sealers, and various medical applications.
“Exposure reduces rapidly with distance,” Torres explains. “And while overall, the RF field background level from household appliances is low, higher levels of exposure to RF fields can occur to workers in the broadcasting, transport and communications industries when they work in close proximity to RF transmitting antennas and radar systems.”
“Although there have been studies reporting a range of biological effects at low levels, there has been no indication that such effects might constitute a human health hazard,” he adds. “But, with the increasing RF coming from device-to-device communications, you begin to have to consider the possibility of adverse health effects.”
Torres points out that RF Shielding Radiant Barrier insulation produced by his company is installed in homes — usually in attics — primarily to reduce summer heat gain and reduce cooling costs.
