5.1 General Information
Radon radiation is radioactive radiation originating from the soil. It can be hazardous to humans if it exceeds certain threshold values indoors.
Certain types of soil can contain high levels of radon, and if the radiation enters indoor spaces in excessive amounts, it is necessary to take measures to reduce indoor radon radiation levels below recommended limits.
5.2 Measurement Methods
5.2.1 Continuous Measurement
Modern radon detectors are available that provide real-time data on radon concentrations.
- The automation system can calculate an average radon level over a selected period.
- Alerts can be triggered if the radon level exceeds the threshold value.
- Notifications can be sent to a mobile phone or an automation system when the threshold is exceeded.
5.2.2 Single-Use Measurement of Average Radon Levels
It is also possible to conduct a one-time radon measurement over a specific period to determine the average concentration. If the result is significantly below the threshold values, it can generally be assumed that radon levels will not later rise dangerously high in that location.
5.3 Radon Control in Different Types of Buildings
5.3.1 New Houses
New houses are typically built with radon mitigation measures in place:
- A ventilation space is created beneath the foundation to allow radon-containing air to flow.
- A pipe is installed from this space to the roof, allowing air pressure differences to direct radon out of the building and into the atmosphere.
- Alternatively, houses can be built on stilts, leaving a natural air gap beneath the structure that prevents radon accumulation indoors.
Because of these measures, radon measurement is usually unnecessary in new houses, as the likelihood of excessive radiation levels is extremely low.
5.3.2 Old Houses
In older houses, radon mitigation was often not considered during construction.
- It is advisable to conduct radon measurement either as continuous monitoring or as a one-time test, providing residents with essential information and the ability to take corrective action if necessary.
5.3.3 Mitigation Options for Old Houses
- If radon levels slightly exceed the recommended thresholds, our system can help reduce concentrations.
- If radon levels are high, the most effective solution is to extract radon from beneath the house before it enters the indoor environment.
