Effectiveness of VENTBOX controlled ventilation in eliminating radon in apartments – Radotín, Czech Republic

Introduction

Radon is a naturally occurring radioactive gas that poses a significant health risk in residential spaces. This study focuses on a project in Radotín, where controlled ventilation systems were implemented to reduce radon exposure and improve indoor air quality.

Objective

To demonstrate the effectiveness of controlled ventilation with the unique system in reducing radon concentrations in apartment buildings.

Methodology

Initial measurements

Above-limit radon concentrations were recorded in fifteen apartments.
Ventilation system design using VENTBOX 400 units with a unique radon elimination mode: A controlled ventilation system with heat recovery was installed, ensuring effective air exchange with minimal energy loss. A specialised mode for radon detection and elimination was implemented, allowing the system to respond dynamically to changes in radon concentration.
Implementation: The system was installed in all selected apartments with elevated radon concentrations, followed by new measurements to assess its effectiveness.

Results

Radon reduction: Following installation, there was a significant decrease in radon concentrations, bringing levels below the recommended safety limits. Measurements were conducted by a certified expert, with independent verification of the results carried out by the State Office for Radiation Protection.
Energy efficiency: The heat recovery component ensured stable indoor temperatures, thereby minimizing heating costs.

Conclusion

The Radotín case study demonstrates that the KORADO controlled ventilation system, featuring a unique radon detection and elimination mode, is highly effective in reducing radon concentrations in residential spaces. This approach not only mitigates health risks associated with radon exposure but also maintains energy efficiency, making it a suitable solution for addressing radon issues in apartments and other buildings. An additional benefit of the system is its ability to regulate CO₂ levels, humidity, and volatile organic compounds.
