Purpose of the work
Can adequate protection against radon buildup according to §123 of the German Radiation Protection Act (Strahlenschutzgesetz, StrSchG) be verified during airtightness tests with the fan pressurization method?

Content of the contribution
Radon is a noble gas which occurs naturally in the uranium-238 decay chain and as such also decays radioactively.
The gas penetrates buildings via leaks/defects in parts of the building envelope in contact with the earth and accumulates in the building. Visitors, occupants and employees in such buildings have a higher risk of developing lung cancer due to long-term low-threshold exposure. Persons suffering from this disease experience a significant loss of quality of life and often die after a long illness.
According to Section 123 of the German Radiation Protection Act all building envelopes of new buildings in Germany have to be radon-proof as of 2018. Constituent states adopted additional measures to prevent radon buildup in designated radon protection areas.
We will demonstrate that we are able to test the building envelope in contact with earth for radon tightness by using test methods in combination with the standard air tightness test equipment which uses the fan pressurization method.
Results and assessment of their significance
We will demonstrate that we are able to test the building envelope in contact with earth for radon tightness by using test methods in combination with the standard air tightness test equipment which uses the fan pressurization method.
Conclusions
This test is feasible in qualitative and quantitative terms
