Electromagnetic Fields

KEMA houses expert knowledge on electromagnetic fields and can perform measurements and calculations as well as provide solutions to reduce electromagnetic fields

The possibility of adverse health effects caused by electric and magnetic fields around overhead power lines has been a topic of investigation and scientific and public debate over the past decades. Several surveys have discussed the association between childhood leukemia and living nearby overhead power lines found in epidemiological studies, although no plausible biological mechanism nor a causal connection have been found. On the basis of the precautionary principle, governments have commissioned research into costs and benefits of measures to reduce the population’s exposure to magnetic fields from power lines. Some governments have included precautionary measures in their policies.

In this field KEMA calculates or measures the magnetic and electric fields from power lines and other sources of EMF. Also, we provide reduction of the magnetic field, applying technical measures such as changes in electrical characteristics, relocation of the line and replacement of overhead power lines by underground cables. Furthermore, KEMA investigates working environments to evaluate the exposure of workers.

KEMA also participates in the Dutch knowledge platform “Electro Magnetic Fields”: www.kennisplatform.nl
