Radon well

A radon well sucks air from the soil, and the radon concentration of the soil air decreases.

In a row house unit, one well can help fix the radon concentration of as many as ten dwelling units. Radon wells are suitable only for coarse gravel, in which the flow field created by the well can progress under the house being repaired.

Radon wells are built outside the house, a few metres from the building. In a row house unit, the well can be located in the yard area. The suitable fan power for the radon well of one low-rise residential building is 150 W. The total cost of a radon well is EUR 3,000–5,000.

A radon well usually reduces the radon concentration by 70–95 per cent.

A radon well is made outside the building. The bottom of the well has 1 m of crushed rock, 0.5 m of which under the exhaust pipe. The crushed rock layer is covered by plastic film and filter fabric, on top of which is silt or sand. The exhaust fan is located under the well ring and cover. The exhaust pipe runs from the bottom of the well to outdoor air.
