Strong electromagnetic fields can pose a hazard to the health of people. The increased use of radio frequency energy for communications, industrial and medical purposes in addition to a general increase in public awareness of the issues has resulted in the introduction of new standards and a proposal for EU Directives and recommendations.

The European Commission has published a Recommendation (1999/519/EC) urging Member States to put in place national provisions setting down maximum limits of non-ionising electromagnetic fields. This Recommendation has closely adopted the ICNIRP (International Commission on Non-Ionising Radiation Protection) 1998 guidelines. It applies to public exposure only. CEI is active on CENELEC (European electrotechnical standardisation body) committees that are developing standards for publication under the Low Voltage Directive and the RTTE Directive and leads the Irish delegation on TC106X.

Guidelines similar to those adopted by the ICNIRP have also been adopted for a proposed EU Directive (93/C77/102), which is intended to ensure the protection of workers from non-ionising electromagnetic fields. The aim of the Directive will be to protect workers only and will not specify levels for public areas. The proposed Directive quotes basic restrictions similar to those contained in the ICNIRP guidelines.

CEI has extensive experience in this area and has assessed many equipment types with complex emissions profiles to ensure compliance with the standards. The threat level is dependent on many aspects of the exposure requiring a wide range of equipment and experience to properly assess the risk. CEI possesses a wide range of radiation hazard monitors, low and high frequency spectrum analysers and transducers that enables characterisation of pulsed, continuous and multi frequency exposure scenarios.

We provide site surveys of EM fields, interpret relevant standards, assist with the reduction of excessive levels and carry out detailed assessments when the levels have been exceeded.

Licensed radio operators are often required by local authorities to provide an independent safety assessment of proposed transmitters to ensure public safety. CEI, as an independent laboratory with the necessary competence, are recognised as the leading provider of these assessments in Ireland. A full report is provided with plots of human exposure level at incremental distances from the mast along with a clear statement of compliance with the appropriate guidelines.
