Fifty-five per cent of these subscriptions are expected to be in the developing world.- Mobile-cellular subscriptions will reach almost 7 billion by end 2014Source: ITU, The World in 2014: ICT Facts and Figures
3 The issue… The electromagnetic fields are unknown and undetectable for people…Lack of regulation and/ornon-compliance...Lack ofcommunication and information to citizens…It can generate a lack of trust, which may become fear…
4 Regulation of non-ionizing radiations Exposure standards:Specifications that limit the exposure of people to the Electromagnetic fields (EMF)Emission standards:Specifications that limit the emission of electromagnetic fields (EMF) from the devices
5 How can global standards help… Facilitate compliance with international standardsStrengthen collaboration among stakeholdersEnsure transparencyEnhance communication with citizens

11 EMF assessment methods Calculations or measurements? EMF assessment method depends on site & environmentCalculations - suitable in many cases, & have significant benefits - accurate, fast & cost effectiveMeasurements - required in very complex environmentsField monitoringField monitoring is effective when working on towers for safetyField surveys can provide public reassuranceContinuous monitoring – limited long term benefit where EMF levels are low and stable ITU-T Recommendations - guidance on both calculation and measurements
