What is Radon and Where is Radon come from ?

what is radon gas

Radon is a radioactive gas that’s usually present in (rough) substrates. When radon penetrates structures in the ground through cracks in the field, joints between walls, the crawl space or through water pipes, then it may pile up and attain high concentrations.

Radon causes roughly 480 cases of lung cancer in Belgium every year. That’s approximately 10 percent of cases of lung cancer.

The threat of lung tumor depends upon two factors:

– The moment spent in your property.

The higher the radon concentration as well as, the longer time you spend inside, the higher the cancer risk. Smokers and also people that are frequently exposed to cigarette smoke have an additional higher risk of lung malignancy on the distant possibility they are also presented to cupping.

Where’s radon from the soil?

Radon is principally located in your back home since the substrate is rugged. But, radon concentrations may also be elevated outside these regions with greater vulnerability. In Flanders, too large radon concentrations in buildings tend to be somewhat less predictable. Such a radon concentration may happen throughout the land.

How do you know whether there’s a lot of radon in your property? On the other hand, the radon concentration may fluctuate significantly from 1 area to another and also from 1 building to another. A straightforward means to understand the radon level in your house has a radon detector which you could see in this report.

In certain buildings, radon can permeate out of the substrate more readily than in other buildings. This is based upon the kind of construction. Additionally, building materials themselves give a home, albeit less compared to the substrate. A closed area, like a home, it may happen strongly concentrated. This is particularly true for poorly ventilated regions.

Estimation is your very best method to understand whether you and your family are at risk from home. A straightforward test with a radon detector suffices to assess the quantity of radon in your house. The radon sensor is a cylinder-shaped jar where a sensitive picture is situated which enrolls the retina. After an investigation of the movie, the radon concentration could be set. Put this sensor for three weeks at the most used area of the home.


The primary source of radon is that the substrate. Notably, in Wallonia high radon concentrations happen frequently due to the rocky substrate. In Flanders, dirt concentrations aren’t as significant. But through cracks, openings, and cracks in the base of the construction, a portion of the retina in the depths stems within the building.

Construction materials

Radon happens in virtually every dirt species and stones.


Passive buildings and much more insulated buildings raise the chance of inadequate ventilation and aeration. The radon that’s discharged from the ground and construction materials will then linger from the construction. Proper ventilation is also vital for excellent indoor air quality (additional information in the venting and aeration of this Fiche).

What will you be able to perform to prevent or reduce radon on your home?

Once the radon concentration in your house is greater than 400 Bq/m³, the FANC advises that you take steps to decrease this concentration under the 400 Bq/m³ and, if possible, beneath the 200 Bq/m³.

Since the concentration measured in the exceeds this value more and more, it’s more suitable to tackle something. Nevertheless, this doesn’t imply that there isn’t any hazard beneath this level. Be as it may, the danger is littler once the attention is reduced.

There are numerous strategies to decrease the radon concentration in the house. These methods are often designed to throw a barrier against flooding or to perform radon-contaminated air. Some are incredibly straightforward and affordable. The principal steps are to increase a barrier from radon and also to drain radon-contaminated air.
