According to EPA’s report of 2003, high concentration of Radon causes lung cancer inducing approximately 21,000 deaths per year in USA and international Agency for Research on Cancer classifies radon as being carcinogenic to humans. According to World Health Organisation, radon is hazardous to health when it’s level in air is above 2.7 pCi/L.
Meanwhile Racine is one of the most Radon affected City. According to Country Radon Info, radon level is above 4 pCi/L in 47% areas of the Racine city, while 22% results between 2 to 3.9 pCi/L radon level. This is quite alarming as the level of radon in most part of Racine is above the action level. EPA recommends the property owners of Racine to seek proper working systems in order that to reduce concentration of radon to safer levels. Radon Mitigation Racine can be done following the steps below.
- Radon testing in your house
- Seeking a System for reduction of Radon
- Maintenance of that system
Selection of a Working System
After Radon testing, you’re some Mitigation methods are followed to lower the level of Radon in your house. There are several Systems being used for Radon Mitigation Racine
· Suction Method
It includes subs lab suction which is suction of radon through the pipes injected in the crushed rocks or soil under the slab floor or suction of radon from the sump pumps. Some houses with drain tiles can also undergo drain-tile suction in which suction is done on perforated pipes. Basement houses that have hollow block walls undergo block-wall suction method in combination with subslab method
· Crawlspace Ventilation
In som cases, ventilation ofcrawlspace can also reduce the level of radon. This method includes use of a fan and can be performed actively or passively. It can reduce the indoor radon levels by the dilution of radon under the house or by lowering the suction of home on the soil. Opening vents and installation of additional ventilators is passive ventilation while using a fan that blows air through the Crawlspace is active ventilation
Covering the earth with highly dense plastic sheet is an effective method for reduction of radon in Crawlspace houses. Radon is drawn by a ventilator pipe and a fan from under the sheet.
Basic part of lowering radon flow in your house is sealing of the cracks in the floor that can also lower the los of conditioned air. Use of sealing alone is not recommended by EPA because sealing has not seen to lower radon on itself. Identifying permanent radon emitting cracks is difficult. Thus it is just additional technique to suction and ventilation.
· Pressurisation of House
This is done by using a fan to blow air from the room to the basement or outdoor. Yet it’s efficiency is limitized because the pressure has to be maintained. The windows and door must not left open to keep the radon out and maintain the pressure.
Other Additional Techniques
Other techniques like heat recovery ventilation and natural ventilation can also be utilized for Radon Mitigation Racine.
