The importance to measure radon wherever you live

Even in areas classified as low risk, radon can potentially pose a problem in indoor air. In fact, the air contained in the soil can have high levels of radon. Thus, depending on the building characteristics, large amounts of radon can penetrate the building even in low risk areas. Likewise, there can be very large local variations, even between two adjacent houses.

It is important to keep in mind that maps only provide information on risk. No map provides information on the actual presence of radon. Certainly, the probability of detecting radon in indoor air is higher in risk areas. The only way to know your radon level is to perform a radon measurement.

I am about to sell a home, should I measure radon?

Although not mandatory, measuring radon during a real estate transactionn is advasible.

The UK regulations only oblige the seller to indicate only the radon risk prescribed by the map defining the risk zones. This means that the regulations do not require the seller to report radon levels inside the building. It is only necessary to indicate whether the building is located in a risk area or not.

This can be misleading because only one measure is a guarantee of the actual radon level. Make sure you have the results of a reliable measurement before you sign the bill of sale.

If there is only a short time, it is still possible to measure radon quickly. With Rapidos, our fast radon detector, it is possible to carry out a measurement of radon so as to have results under 1 month. In addition, do not hesitate to ask for the insertion of a clause in the deed of sale. It may mention that the terms of the sale will be conditioned by a radon measurement and that the cost of a possible mitigation must be shared.
