Radon, a radioactive noble gas, is the second leading cause of lung cancer after smoking. Current research shows that around five percent of cancer-related deaths in the population are linked to radon in homes.
We are specialists in sound, radon, and moisture protection. With modern polyethylene building materials, we enable fast, efficient, and safe construction.
According to a survey by the Federal Office for Radiation Protection, many people underestimate the risks of radioactive radon in the home. Only about 23% of respondents express concern about radon in the environment and reliable radon protection – even though it is the largest source of average annual radiation exposure. Radon in the home cannot be seen, smelled, or tasted. The concentration of radon indoors can only be determined by a radon measurement.
Products from Gefinex prevent radon from entering buildings. The radon protection membrane is highly tear-resistant, extremely durable, and particularly easy to install.
Estimation of radon concentration in the soil for a 3×3 kilometer grid. Statements about individual buildings can only be made through specific measurements taken within the respective building.
The Act on the Reorganisation of Radiation Protection Law also regulates protection against radon. Since 2019, protection against high radon concentrations in workplaces has been expanded to ensure that, in the long term, no workplace exceeds an annual average radon concentration of 300 becquerels per cubic meter.
“Anyone constructing a building with occupied rooms or workplaces must take appropriate measures to prevent or significantly impede the entry of radon from the ground. This obligation is deemed fulfilled if
“Anyone who, in the course of structural alterations to a building with occupied rooms or workplaces, carries out measures that significantly reduce the air exchange rate should consider implementing radon protection measures, provided such measures are necessary and reasonable.”
