Procedure details

The Radiation Protection Act regulates at which workplaces in Germany the radon activity concentration must be measured. Such an obligation exists in radon precautionary areas at workplaces in basements or first floors as well as nationwide in work areas already known to have elevated radon concentrations, such as waterworks, mines or radon healing tunnels. The responsible state authorities can also order measurements at other workplaces.

Providers who wish to carry out the legally required measurements of radon activity concentrations at these workplaces must be recognized by the Federal Office for Radiation Protection (BfS). Recognition serves to ensure the quality of the measurements.

The documents and evidence submitted together with the application for recognition are checked by the BfS. If the requirements are met, the provider is recognized. Recognition is subject to a fee and is valid for an unlimited period. However, it can be revoked or withdrawn if the requirements are no longer met. Recognition is not transferable.

  • You have suitable measuring devices.
  • You have suitable equipment and procedures for evaluation.
  • You have a suitable quality assurance system.
  • You participate in quality assurance measures by the Federal Office for Radiation Protection.

  • Required Documents

    • Copy of the accreditation certificate including scope of accreditation and
    • Documentation of the quality management system

    Further information on the required documents can be found on the website of the Federal Office for Radiation Protection. Please also take the opportunity of a preliminary discussion to clarify the documents required for you.

You can apply online or by e-mail to the Federal Office for Radiation Protection (BfS) for recognition as a body for measuring radon activity concentrations at workplaces. You should clarify in a preliminary discussion with the BfS whether there are any possible reasons that could prevent recognition.
