If the reference value of 300 Bq/m³ is exceeded at at least one workplace, the radon exposure at the workplaces concerned is to be reduced by means of structural measures.

Advice from trained experts in structural radon protection will help you choose the right remediation measures! In most cases, it will be possible to achieve a permanent reduction in radon concentration with relatively little effort if a professional approach is taken. Further information on remediation measures can be found here.

If a new measurement (control measurement) shows compliance with the reference value, no further measures are necessary. The procedure for the control measurement is the same as for the initial measurement and must be carried out by an authorized monitoring body.

If it is not possible to reduce the radon concentration in the workplace to below the reference value with economically justifiable measures, you must comply with further obligations.
