Although there is considerable public concern about possible effects of mobile telephone base-stations on healthand wellbeing no studies on that issue have been published so far. Since the introduction of modern mobiletelecommunication in the early 1990ies exposure of the public to high-frequency electromagnetic fields (EMF)has about doubled [1], at least in Europe. Nevertheless, it has been stated [2] that exposure to emissions frommobile phone base-stations are not of primary interest while effects of mobile telephones themselves should beinvestigated. However, there is a fundamental difference between exposure from mobile phones and their base-stations that has not been considered: while exposure to emissions from mobile phones is intermittent andtypically of short duration, those from base-stations could be 24 hours a day persisting for years. There ispresently no consensus about long-term effects of EMFs. The International Commission on Non-IonizingRadiation Protection (ICNIRP) declared such effects as not established [3]. Evidence in favor and against thisposition is weak, because studies on that issue are scarce and some suffer from methodological deficiencies.From a precautionary point of view, however, the evidence for long-term effects is sufficient to warrant athorough examination of possible effects on wellbeing and health from exposures to mobile telephone base-stations. It has been argued that if there are detrimental effects from exposures to modern telecommunicationthen we should have recognized such effects earlier due to implementation of powerful radio and televisiontransmitters.
