Abstract

Limiting liability with positioning to minimize negative health effects of cellular phone towers Pearce JM. Limiting liability with positioning to minimize negative health effects of cellular phone towers. Environmental Research. Available online 29 November 2019, 108845. Highlights • Cellular phone networks demand widespread human exposure to radio-frequency radiation (RFR). • Cellular phone base stations density & power output increasing global human RFR exposure. • Already enough medical-scientific evidence to warrant long-term liability concerns. • To protect cell phone tower firms, companies should seek to minimize human RFR exposure. Abstract The use of cellular phones is now ubiquitous through most of the adult global population and is increasingly common among even young children in many countries (e.g. Finland, where the market for smart phones is nearly saturated). The basic operation of cellular phone networks demands widespread human exposure to radio-frequency radiation (RFR) with cellular phone base stations providing cellular coverage in most areas. As the data needs of the population increase from the major shift in the source of Internet use from personal computers to smart phones, this coverage is widely predicted to increase. Thus, both the density of base stations and their power output is expected to increase the global human RFR exposure. Although direct causation of negative human health effects from RFR from cellular phone base stations has not been finalized, there is already enough medical and scientific evidence to warrant long-term liability concerns for companies deploying cellular phone towers. In order to protect cell phone tower firms from the ramifications of the failed paths of other industries that have caused unintended human harm (e.g. tobacco) this Current Issue summarizes the peer-reviewed literature on the effects of RFR from cellular phone base stations. Specifically the impacts of siting base stations are closely examined and recommendations are made for companies that deploy them to minimize their potential future liability. ncbi.nlm.nih.gov Excerpts A review article of the health effects near base stations concluded that deployment of base stations should be kept as efficient as possible to minimize exposure of the public to RFR and should not be located less than 500m from the population, and at a height of 50m (Levitt and Lai, 2010).... There are several first steps a cellular phone company can take to minimize human exposure particularly of the most vulnerable populations. First, voluntarily restrictions can be made on the placement of cellular phone base stations within 500m of schools and hospitals.... The second technical hurdle is more challenging. Ideally, all cell phone users would have coverage while minimizing the population density near cellular phone base stations (thus minimizing health impacts) .... The cell phone industry should also consider cell splitting, small cell deployment, beam and null steering antennae as possible technical means for reducing RF exposure. Moreover, more research on cognitive radio should also be conducted, so that the overall RF exposure is reduced.... Finally, exposed companies should consider funding large-scale epidemiological studies with personal dosimeters for strict dose measurement and straight-forward tissue exposure. By quantifying the human medical threat themselves, more appropriate long-term planning can be made to minimize the risk of liability from unintended human harm due to cellular phone base station siting.

Main findings

This article summarizes peer-reviewed literature on radio-frequency radiation (RFR) from cellular phone base stations, focusing on how siting/positioning may minimize potential negative health effects and future liability. It notes that direct causation of negative human health effects from base-station RFR has not been finalized, but argues there is sufficient medical/scientific evidence to warrant long-term liability concerns and recommends minimizing public exposure (e.g., siting away from schools/hospitals).

Outcomes measured
