The Municipality of Seneffe launches the Radon Action initiative, allowing residents to measure the presence of radioactive gas in their homes.

Radon, a naturally occurring radioactive gas found in the soil, can infiltrate buildings. Although colorless, odorless, and invisible, prolonged accumulation indoors can pose health risks, particularly to the lungs. The only way to determine radon concentration in a home is through measurement.
As part of this campaign, residents can order a detector to be placed for three months in the most occupied room on the ground floor, typically the living room or a bedroom. The process is straightforward: order the device at www.actionradon.be, follow the provided instructions for placement, and then return it after three months for analysis. You will receive your results along with tailored recommendations.
The detector costs €20, which includes analysis and, if necessary, guidance on corrective measures. In many cases, simple solutions such as improved ventilation can significantly reduce radon concentration.
The campaign traditionally runs from October 1st to December 31st, subject to detector availability. The measurement period then extends for three months, coinciding with the heating season when buildings are generally less ventilated. Further information is available at www.actionradon.be.
