“…For each of the considered exposure circumstances, average specific absorption rates (SAR) for the brain and the whole body were derived from the literature (Gati et al 2009;Hadjem et al 2010;Huang et al 2014;Lauer et al 2013;Persson et al 2012;SEAWIND 2013;Vrijheid et al 2009). To obtain a cumulative daily brain and whole body dose for each study participant, the SAR values were multiplied by the average exposure duration per day for each exposure situation and summed up to one single brain and whole body dose measure.…”

BackgroundThe aim of this study is to investigate whether memory performance in adolescents is affected by radiofrequency electromagnetic fields (RF-EMF) from wireless device use or by the wireless device use itself due to non-radiation related factors in that context. MethodsWe conducted a prospective cohort study with 439 adolescents. Verbal and figural memory tasks at baseline and after one year were completed using a standardized, computerized cognitive test battery. Use of wireless devices was inquired by questionnaire and operator recorded mobile phone use data was obtained for a subgroup of 234 adolescents.RF-EMF dose measures considering various factors affecting RF-EMF exposure were computed for the brain and the whole body.Data were analysed using a longitudinal approach, to investigate whether cumulative exposure over one year was related to changes in memory performance. All analyses were adjusted for relevant confounders. ResultsThe kappa coefficients between cumulative mobile phone call duration and RF-EMF brain and whole body dose were 0.62 and 0.67, respectively for the whole sample and 0.48 and 0.28, respectively for the sample with operator data. In linear exposure-response models an interquartile increase in cumulative operator recorded mobile phone call duration was Conclusions 3A change in memory performance over one year was negatively associated with cumulative duration of wireless phone use and more strongly with RF-EMF dose. This may indicate that RF-EMF exposure affects memory performance.

“…The denser the network, the more handovers or location area updates have to be expected. A recent European study with software modified mobile phones found that the average output power was approximately 50% of the maximal value, and that output power varied up to a factor 2 to 3 between countries and network operators (Vrijheid et al 2009). …”

BackgroundConcerns of the general public about potential adverse health effects caused by radio-frequency electromagnetic fields (RF-EMF) led authorities to introduce precautionary exposure limits, which vary considerably between regions. It may be speculated that precautionary limits affect the base station network in a manner that mean population exposure unintentionally increases. AimsThe objectives of this multicenter study were to compare mean exposure levels in outdoor areas across four different European cities and to compare with regulatory RF-EMF exposure levels in the corresponding areas. MethodsWe performed measurements in the cities of Amsterdam (the Netherlands, regulatory limits for 3 ConclusionsAll exposure levels were far below international reference levels proposed by ICNIRP (International Commission on Non-Ionizing Radiation). Our study did not find indications that lowering the regulatory limit results in higher mobile phone base station exposure levels.
