Because radon gas concentrations fluctuate dramatically based on barometric pressure shifts, mountain wind squalls, and heating stack effects, cheap charcoal canister test kits frequently yield misleading results. We deploy NRPP-certified electronic continuous radon monitors (CRMs) that record hourly picocurie readings, barometric trends, and tamper metrics to deliver authoritative 48-hour diagnostic reports for real estate transactions and family health peace of mind.
We utilize state-of-the-art Sun Nuclear and Radalink pulsed-ion chamber monitors calibrated annually at certified radiological laboratories. Unlike passive charcoal tests, our CRMs log hourly radon levels, ambient temperature, relative humidity, and barometric pressure trends.
Strict home purchase contingency deadlines require rapid, legally binding verification. Our certified specialists place monitors under closed-building conditions, retrieve devices promptly after 48 hours, and deliver comprehensive PDF reports with hourly graphs the same afternoon.
Prior to installing a mitigation system, proper diagnostic testing is essential. We drill 1/2-inch micro test holes across your basement slab, apply test suction, and measure pressure differential with digital micromanometers to precisely size suction pits and fan capacity.
To ensure test validity during real estate escrow, our electronic monitors incorporate motion accelerometers and power-loss sensors that detect any unauthorized movement, open window drafts, or device tampering, ensuring 100 percent EPA compliance.
Closed-building conditions require all exterior doors and windows to remain closed for 12 hours prior to and throughout the 48-hour test period, except for normal entry and exit. Normal heating and cooling may operate.
Monitors are placed in the lowest livable area of the home—typically a finished or unfinished basement, or ground-floor living room—elevated 20 inches off the floor away from exterior drafts.
Results are analyzed immediately upon retrieving the continuous monitor at the 48-hour mark, and a certified PDF report is emailed to all parties the same day.
