The rapid development of roof-top communication sites on high-rise buildings, especially by telecommunication service providers for cell phones, smart phones and other wireless communication has emphasized the need for a controlled environment. Prolonged exposure to Radio Frequencies could cause body tissues to heat up if in excess of the limits identified by Health Canada, leading to health problems. This could effect roofers, refrigeration personnel, RF-workers and others working or spending time on roof-tops. Where antennas mounted on roofs or in other areas accessible to the public transmit energy fields in excess of limits identified in Safety Code 6, special warning signs have to be installed advising of the danger of potentially harmful electromagnetic radiation.
RF workers, working on towers or in close proximity of active antennas often have radiation detectors that send off audible and visual alarms when the pre-set exposure limits have been exceeded. This typically results in reducing power to the transmitting antenna(s) or reducing the power to acceptable limits.
Alpha-Beta Communications Group Inc. does site analysis and calculates the projected power density field of transmitting antennas to ensure that the system works within safe limits as identified in Safety Code 6. For more information, please go to RF Exposure Compliance.
