According to health experts, radon is the leading cause of lung cancer among non-smokers, and the second leading cause of lung cancer deaths in the general population. Radon is a naturally occurring gas that is radioactive, colorless, tasteless and odorless. When indoor radon levels are above 4 pCi/L, the EPA recommends the installation of a radon mitigation system. The first step to take is to choose a Radon Systems Maintenance in Pittsburgh PA contractor, as the lowering of radon levels requires specific knowledge and skills. Many states require radon mitigation professionals to be licensed, certified, or registered.
When radon is present, it easily finds a way into a building or home because interior air pressure is lower than that of the ground around the foundation. The building acts as a vacuum, sucking radon gas in through cracks in the foundation or through openings around pipes and drains.
Radon testing devices used by Radon Systems Maintenance in Pittsburgh PA, are categorized as passive or active. Passive systems do not require electricity and are available over the counter. Passive systems consist of a charcoal-based collection medium that the user places in the lowest livable area of the home. After two to seven days, the collection is sent to a laboratory for analysis. Active devices require electricity, and detect and record radon levels continuously for up to a year. How long is determined by the type of detection device used. The EPA recognizes 15 types of radon test devices.
Radon mitigation systems are the means used by Radon Systems Maintenance in Pittsburgh PA, to lower indoor radon levels. Radon mitigation is any process or method utilized to reduce radon gas levels in interior breathing zones. The EPA preferred method of mitigating radon indoors is accomplished primarily through a ventilation system that pulls radon from beneath a house or structure and vents it to the outside. The type of foundation, be it a basement, crawl space or slab, usually determines which radon mitigation system will be recommended for installation by Radon Systems Maintenance in Pittsburgh PA.
A radon reduction system requires Radon Systems Maintenance in Pittsburgh PA, if it is to remain in good operating condition. Active mitigation systems are fan powered and include a warning device, usually a manometer, whose level should be periodically checked. The heat recovery ventilator system (HRV) needs bi-yearly cleaning and inspection, as these run 24-hours a day, 365-days a year.
