Nevada Indoor Air Quality Guide
Las Vegas has the fastest new construction rate — creating VOC exposure in new homes
Zone 2 — Moderate potential (2-4 pCi/L)
Radon Levels in Nevada
Average Radon Level
2.8 pCi/L
EPA Zone
Zone 2
Nevada is mostly Zone 2. However, areas near Reno and the Sierra Nevada foothills show Zone 1 readings. Las Vegas valley is generally lower due to desert geology.
📋 Testing recommended
Even in Zone 2, the EPA recommends testing every home. Radon varies house by house — your neighbor's low reading doesn't guarantee yours is safe.
Top Indoor Air Hazards in Nevada
Volatile Organic Compounds (VOCs)
HIGH RISKVOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Dust Mite Allergens
MODERATEDust mites thrive in warm, humid environments and their waste proteins are among the most common indoor allergens. A typical mattress contains 100,000 to 10 million dust mites.
Poor Ventilation (Stale Air)
MODERATEModern energy-efficient homes trap pollutants indoors. Without adequate ventilation, CO2, VOCs, and airborne pathogens accumulate to levels 2-5x higher than outdoors. This is called sick building syndrome.
Nevada Climate & Air Quality Factors
Desert climate with extreme heat drives year-round AC use. Las Vegas construction boom means many new homes with VOC off-gassing from materials. Dust and particulate matter from construction is common.
