How to identify and assess CEM

Published on: 25/02/2019

The Royal Decree 299/2016, of 22 July, on protection of the health and the workers safety against the risks related to the exhibition to electromagnetic fields, establishes that is owed to determine what teams generate CEM and if it is required to carry out an evaluation specific to CEM in the workplace, to know its risk level.

When the team issuer of CEM is set aside for use by the general population, he must comply with the Recommendation 1999/519/EC regarding the exhibition of the general public to CEM, built in to our legislation in the Royal Decree 1066/2001. This regulations limits the intensity of the fields so that the exhibition to the same does not cause adverse effects in the town, being these indexes for the strictest general public that for workers. For this reason, in the workplaces with teams and facilities that comply with this regulations, it will not be necessary to carry out an evaluation specific to CEM.

In other workplaces in which is not thus, can exist a risk of exhibition to CEM where yes it will be necessary to carry out a specific evaluation to CEM.

There are different applications that help to the employer to discern when is necessary and when not a specific evaluation. Offer the link to the application of the INSST Electromagnetic fields (CEM) and to applications of the INRS (France): Oseray and the Calculator GOES/VLE of CEM:

  • Electromagnetic fields (CEM): INSST
    The application is based on the information included in the Technical Guide for the evaluation and prevention of the risks derived from the exhibition to CEM in the workplaces.

  • Oseray: INRS (France)
    Indicates if it exists the risk of exceeding limit values of applicable exhibition according to the categories of workers. Therefore, allows defining which are sources that require a possible evaluation in depth.

  • The calculator GOES/VLE: INRS (France)
    Directs on limits of stock to determine in a very simple way securities that trigger the stock (GOES) and limit values of exhibition (VLE) that are not owed to exceed in the event of exhibition to electromagnetic radiation of monofrequency for frequencies between 0 and 300 GHZ.
