Radon risk areas

Radon gas occurs naturally in soil and rocks. Therefore, ground air almost always contains radon. Since air pressure is usually lower indoors than outdoors, radon can be drawn into houses from the ground. If large amounts of ground air leak into the house, there is always a risk of high indoor radon levels.The radon situation in the municipality has been surveyed and presented on a radon risk map showing areas with low, normal, and high risk for ground radon. However, it has been found that the classification of the soil is not particularly significant in determining how many houses with elevated radon levels are discovered. The most important factor is whether there are gaps in the foundation slab or floor structure that allow ground air to enter the house.If you have questions about the data, contact [e-mail].
