Electromagnetic (E-field) and magnetic (H-field) measurements
Since 2004 Ramboll has offered independent consultancy on EMR measurement.
Ramboll can perform electromagnetic measurements with highly specialised equipment which is certified every two years. A very broad range of E-field frequencies up to 6GHz are covered - radio, television, mobile, Wi-Fi, local networks and many others services. The measurements are performed in accordance with Ramboll’s quality system, which complies with ISO 9001. Ramboll also has equipment to perform measurement of H-field (magnetic) frequencies, which is often measured in industrial production connected to welding of plastic etc.
Over the years Ramboll has performed EMR measurements in Denmark, Sweden, Norway, England and the USA on items ranging from trains and power lines through various radio systems to radar and sat.com systems.
Reports are elaborated with a focus on the client’s need to learn about the issue without having any specialised knowledge about the subject. It is a difficult task to measure and report about electromagnetic radiation and Ramboll’s employees are specially trained to perform such tasks.
EMR health and safety
The European Commission has published directive 2013/35/EU regarding the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields) (20th individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC) and repealing Directive 2004/40/EC. All EU member states had until the end of June 2016 to transpose the directive. For the first time ever workers are now protected by law against exposure to magnetic fields; so far only public and residential areas have been protected.
According to the directive, employers are allowed to make a theoretical assessment of whether the limit values for E-Field (electrical field) and H-Field (magnetic field) are upheld. If in doubt, measurements are to be made. Special consideration is to be taken towards pregnant women and/or personnel with medical implants. If the limit values are exceeded, and the area where this occurs has not been clearly marked or closed off, the employer can be held responsible. Therefore it is of the utmost importance to know the EMR levels according to the limit values.
