Radalink

What Radalink does

Radalink, Inc. is a privately held Georgia corporation headquartered in Atlanta that provides radon measurement services to home inspectors through an equipment-plus-laboratory subscription model. The company operates an NRSB-accredited radon chamber facility (active since 1988) and manufactures and leases AirCat blind continuous radon monitors under its core OnePrice Program. The AirCat devices detect radon-222 via pulsed ionization chambers, capture hourly data on radon concentration, temperature, barometric pressure, and relative humidity, and upload encrypted results over Bluetooth for lab review. Radalink issues NRSB/NRPP-certified reports — usually within one hour during business hours — and handles inspectors' state regulatory compliance, calibration, and QA documentation.

The company monetizes primarily through recurring monthly monitor leases (OnePrice flat-rate subscriptions, Per-Test usage-based subscriptions priced at $90/month per monitor plus $30 per test), a one-time $150 account activation fee, and a $495 Kick-Start 'Business In a Box' bundle that combines certification training, a 3-month equipment lease, and marketing materials. Ancillary revenue comes from 16-hour Radon Measurement Certification courses ($150 for affiliates, $450 for non-affiliates) that carry continuing-education credits for ASHI, InterNACHI, NRSB, NRPP, and multiple state agencies. Distribution runs through a channel-partner model: home inspectors apply, sign up via AdobeSign, complete phone orientation and training, and lease monitors; the MyRadalink portal handles account management, QA records, and lead routing. Homeowners access the network via a zip-code-based inspector finder on radalink.com.

Radalink was founded by Terry Howell, operating continuously since 1988 out of 5599 Peachtree Rd., Atlanta, with a current headcount of 11-50. The business is bootstrapped and founder-led, with no disclosed institutional investors or M&A activity. Beyond recurring leases and certification, the company runs a Radon Business Boost opt-in advertising program that funnels homeowner leads to participating inspectors, and it exhibits at industry events such as Inspection Fuel conferences to recruit new affiliates.

Emerging players

• Airthings: Consumer and pro-grade smart radon monitors with continuous detection and app connectivity. Comparable as a radon detection hardware and software provider, though positioned more toward consumer/DIY buyers than the inspector-affiliate lab model.

Direct peers

• AccuStar Labs / Air Chek: Mail-in radon test kit and laboratory analysis provider widely used by home inspectors and homeowners. Operates a competing NRPP/NRSB-certified lab model; relevant direct competitor to Radalink's certified analysis and equipment offering.
• RTCA (Radon Testing Corporation of America): Multi-state radon measurement, mitigation, and laboratory services provider serving real estate and home inspector markets. Comparable as a service-based radon testing and lab competitor with overlapping inspector customer base.
• RSSI (Radon Specialties / Radon Systems Services): Radon testing, mitigation, and equipment provider operating in multiple US states. Relevant regional/scale peer for radon lab and inspector-channel services comparable to Radalink's offerings.
• Radon Environmental: Canadian radon measurement, mitigation, and laboratory services company. Comparable as a NRSB-equivalent certified lab and inspector-channel radon testing service operating in North America.
• PRO-LAB / Alpha Energy Laboratories: Radon test kit manufacturer and analytical laboratory serving home inspectors and homeowners for residential radon measurements. Comparable as a certified lab and mail-in radon testing peer.

Broad incumbents

• Sun Nuclear (SunRADON): Radiation detection instrumentation manufacturer that has produced continuous radon monitors and radon calibration/test equipment used by labs and inspectors. Comparable as an established radon hardware/equipment peer rather than a competing lab service.
• First Alert / BRK Electronics: Major consumer safety products brand offering retail radon detectors and home safety devices. Comparable as an adjacent consumer-facing radon product manufacturer rather than a direct lab/inspector competitor.
• Honeywell International (Residential): Large diversified industrial and home products conglomerate producing a wide range of residential sensors, including air quality and radon-adjacent monitoring products. Comparable only as a broad incumbent in indoor air quality; does not directly compete in inspector-channel lab radon testing.

Others

• National Radon Proficiency Board (NRPP) / NRSB-accredited labs ecosystem: Standards and certification bodies (NRPP, NRSB) that govern the radon measurement profession and accredit competing devices and labs. Relevant not as a competitor but as the regulatory accreditation context within which Radalink and peers operate.
