• The BfS will check your registration and send you a confirmation of receipt.
• In the case of the comparative test, the BfS will send you stickers to be attached to the devices (identification code) once participation has been approved. Send the devices to the BfS radon calibration laboratory in Berlin. After completion of the exposures, the devices will be returned to you.
• If you are participating in a calibration exposure, please assign your own identification codes to the individual devices. Send the devices to the BfS radon calibration laboratory in Berlin. After completing the exposure, please arrange for your devices to be collected from the BfS.
• You evaluate the devices and send the results digitally to the BfS. You will receive a form for this purpose after completing the exposure.
• You will receive the individual report by e-mail.
• You will receive the notification of costs by e-mail or via your Elster organization account. You then pay the costs.

Regular participation is mandatory for

• officially designated measuring stations that issue measuring devices for monitoring occupational radiation exposure due to radon;
• recognized bodies that have been approved by the BfS for the measurement of radon-222 activity concentrations or institutions in the approval process.

• If applicable, device description with information on the device type

The comparative test is offered once a year, the calibration exposure usually twice a year. The registration deadlines are announced in December of the previous year.

Participation in the proficiency tests as a quality assurance measure is required every 2 years for recognized bodies.

Participation in the proficiency tests as a quality assurance measure is prescribed by the responsible state authority for officially designated measuring bodies.
