COMMON RADON MITIGATION STRATEGY TODAY
Locate cracks and openings to soil and seal them
2. DRILL CHECKPOINTS
Drill holes to check the pressure field in the crawl space or in the sub-slab.
3. MAKE A UNIFORM PRESSURE FIELD
Make a uniform pressure field opening holes through walls in the crawl space.
4. APPLY MEMBRANES
Apply additional waterproof membranes to exterior walls, if needed.
5. BUILD THE PIPING SYSTEM
Install an exterior or interior piping system and one or more fans to control pressure and exhaust radon.
Connect sensors and existing HVAC system control units to our cloud. Install minimally invasive air purifiers, if needed.
MONITOR THE AIR QUALITY AND DRIVE SYSTEMS
Continuously monitor radon and optimize already installed HVAC systems to solve the radon and air quality problems. Sensors, purifiers and HVAC systems send data to and are driven through our cloud.
EXAMPLES OF RADON MONITORING AND MITIGATION
MONITORING THE RADON CONCENTRATION
Higher values of the concentration are recorded when the school is closed (the nights and weekends) due to the lack of air exchange and consequent radon buildup. When the school is open, the radon concentration drops below the legal limit of 300 Bq/m³. This strongly suggests that even in this radon prone building, radon can be kept under control without invasive work on a mitigation system. The plot shows three sensors working in parallel.
DRIVING AN HCVA SYSTEM IN A WATER RESERVOIR
Radon concentration measured by our sensor in a water reservoir, while driving the HVAC system through a smart relay connected to our cloud. The HVAC is turned on when the radon concentration exceeds 180 Bq/m³, and is turned off when it falls below 120 Bq/m³ (grey bands). The gold band shows the period at the end of the measurement when the HVAC was off and the radon concentration drifted to a higher value.
PURIFYING THE AIR IN A CELLAR
In some places there is no HVAC system and it is too expensive or simply impossible to install one. Thanks to our RADOM monitoring and mitigation system it is simple to minimize the dose to the lung (i.e. the damage from radiation) and the risk of lung cancer. We measured in a cellar how turning on and off the system modulates the effective dose.
