Radiofrequency (RF) energy is becoming increasingly common in today's society. Items such as cell phones, Bluetooth devices, medical devices, and major radio transmission sources such as radar stations, television and radio broadcasting stations, all contribute to the RF energy emissions. The placement of cell phone towers in residential areas and on rooftops of apartment buildings has raised awareness and increasing concern for the potential effects of RF exposure on human health.
RF energy is the portion of the electromagnetic spectrum with frequencies ranging from 3 kHz to 300 GHz. Intense RF energy may cause tissue heating and excitable tissue stimulation from short-term (acute) exposures. Health Canada's Safety Code 6 indicates exposure limits of RF energy for the protection of adverse human health impacts.
G2S has conducted RF Surveys at residential apartment buildings with wireless panel antennas (cell phone service providers) installed on the roof to determine if exposure levels throughout the building fall below Health Canada's Safety Code 6 limits. G2S works in coordination with Dr. Natalia K. Nikolova, P.Eng. (ON), a Professor at McMaster University, Hamilton. She has been a faculty member of the Department of Electrical and Computer Engineering in McMaster University since 1999 where she teaches courses related to electromagnetic fields and waves, antennas, and radio-frequency (RF) and microwave engineering. She has consulted for more than 6 years in the areas of microwave antennas, radar imaging and detection, and electromagnetic high-frequency computer-aided design. She has been working on collaborative projects between McMaster University and industrial partners related to the RF hazard evaluation of mobile devices and radiation sources for the last three years. Prof. Nikolova is a registered Professional Engineer in the province of Ontario and a Fellow of the Institute of Electrical and Electronic Engineers (IEEE).
Radiofrequency surveys can include:
- Residential apartment or home surveys
- Commercial or workplace surveys
- Schools or municipal surveys
