Frequently Asked Questions
Straight answers about radon testing, health risks, and mitigation in the Capital Region.
What is radon and where does it come from?
Radon is a naturally occurring, radioactive gas that is colorless, odorless, and tasteless. It forms from the natural decay of uranium present in soil, rock, and water. Radon seeps up from the ground and can enter homes through cracks in foundations, floors, walls, sump pumps, or other openings, where it may accumulate to harmful levels indoors — often higher than outdoors.
What are the health effects of radon?
Long-term exposure to elevated radon levels is the second leading cause of lung cancer in the United States (after smoking), according to the EPA and Surgeon General. It accounts for about 21,000 lung cancer deaths annually. When inhaled, radon's radioactive decay products damage lung tissue over time. The risk is higher for smokers, but non-smokers are also affected. There is no known safe level, though risks increase with higher concentrations and longer exposure.
How can I find the radon levels in my home?
The only way to know your home's radon levels is through testing. Use EPA-approved short-term (2–7 days) or long-term (3+ months) test kits, available online, at hardware stores, or from professionals. For accurate results, follow closed-house conditions (windows/doors closed except for normal entry). In the Capital Region of NY, Radon Mitigation of Albany offers professional testing for reliable, precise measurements.
How often should I test my home for radon?
The EPA recommends testing every home at least once, with follow-up testing if levels are elevated. Retest every 2 years as routine maintenance, or sooner if you make major renovations, change occupancy (e.g., using a basement more), or install a mitigation system. Radon levels can fluctuate due to settling foundations, weather, or home changes — regular testing ensures ongoing safety.
When should I mitigate radon in my home?
The EPA recommends fixing your home if radon levels are 4 pCi/L or higher (the action level), and considering mitigation for 2–4 pCi/L. Mitigation typically involves installing an active soil depressurization system to vent radon safely outdoors, often reducing levels by up to 99%.
