Low-frequency electromagnetic fields in the workplace

Radiansa offers a measurement services of low-frequency electromagnetic fields in industrial, commercial, residential, and public buildings, tailored to your requirements:

  • Precautionary exposure assesments
  • ICNIRP public and occupational exposure limits
  • EC/2004/40 Complicance testing to EN50499 standard
  • Lipoatrophia Semicircularis solutions and diagnostics
  • Local regulations

Industrial exposure assement

Limiting the exposures of workers to electromagnetic fields is the subject of Directive 2004/40/EC of the European Commision, the "Physical Agents Directive". While implementation of the 2004 Directive was delayed for a further 4 years by Directive 2008/46/EC, and will not come into force without an additional provision to allow continued operation of magnetic resonance imaging in hospitals, the aim of the EC Physical Agents Directive is to make the recomendations specified by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) a legal requirement across Europe with respect to the exposure of workers to electromagnetic fields.

In 2010, ICNIRP published exposure limits for workers upon which the new Physical Agents Directive, officially expected in 2012, will be based. While the Directive has not yet been ratified, the measurement protocol for assessing compliance has been published by CENELEC, (the European Committee for Electrotechnical Standardization) in EN 50499, entitled 'Determination of workers exposure to electromagnetic fields'. Radiansa Consulting provides measurement and risk assessment services to check compliance with the Physical Agents Directive according to EN50499.

Offices and other workplaces

Electromagnetic field levels in offices are generally far below the reference levels for occupational exposure, however exposures to low intensity electric and magnetic fields continue to cause much concern among employees. Radiansa provides a full and discreet diagnostic of potential health problems associated with magnetic fields in your office or building, together with practical advice on reducing magnetic fields to acceptable levels.

A statistical link between magnetic field exposure and childhood cancers suggests a precautionary approach should be adopted regarding exposures to pregnant women in the workplace. Despite the lack of firm scientific evidence, the possibility that exposures to low-frequency magnetic fields at levels far below current recomended exposure limits could be harmful. The adoption of a precautionary approach in the light of this doubt, particulary for pregnant women and by extension women of childbearing age, is entirely reasonable. Very often, the simple and costless expedient of moving a desk a metre or two will reduce magnetic field exposure significantly.

Another interesting example of where current interpretation of ICNIRP exposure limits to electromagnetic radiation has been shown to be inadequate is the occurrence of the disorder known as Lipoatrophia Semicircularis, predominately in office workers; electric fields responsible for this condition occur at around 5 times less than ICNIRP recommendations for public exposure.
