SunRADON

What SunRADON does

SunRADON LLC is a Florida-based, privately-held manufacturer of radon and indoor air quality monitoring equipment, operating continuously in the radon-detection space since 1987. The company was formally separated from Sun Nuclear Corporation in 2019 as a stand-alone LLC headquartered in Melbourne, FL, with in-house R&D, manufacturing, and calibration facilities. Its core technology is a patented solid-state detector that continuously measures radon by detecting alpha particles from radioactive decay and reporting hourly readings, paired with proprietary touchscreen hardware (XP Family), Bluetooth/USB-C/cellular connectivity, and a multi-OS software suite (OneRADON) that spans mobile, desktop, and cloud.

The company operates a two-segment business model. On the professional side, it sells continuous radon monitors (XP at $895, XP+ with environmental sensors, XP+Cellular with LTE) primarily to licensed radon measurement professionals, home inspectors, and radon mitigators; these buyers are gated by NRPP, C-NRPP, and NRSB certifications, all of which SunRADON holds. It monetizes the installed base through layered subscriptions: OneRADON ($164/yr for cloud, reports, and bundled free annual calibration), OneRADON+Cellular ($29/mo), and SunLAB ($79-$149/mo, providing NRSB-certified laboratory review and state-compliant reporting across 33 states), plus rental tiers. On the consumer side, the lüft and lüft PRO plug-in monitors ($179-$249) target homeowners and mitigators with WiFi-connected multi-sensor IAQ monitoring. Distribution is hybrid: direct e-commerce via sunradon.com, five authorized international distributors (Canada, Hong Kong, South Korea, China, Spain), Amazon Canada for lüft, and community-driven channels including InterNACHI (10% member discount), franchise partner programs, an NRPP-approved CE course via CERTI, and an affiliate (20% commission) plus trade-in program.

Customer feedback signals a sticky professional user base: Pillar-to-Post (18-year customer), Katz Home Inspection, Ohio Radon Mitigation, and RCI Service Property Inspection (20-year customer) all cite reliability and customer service as primary reasons for retention. SunRADON reports 10+ million homes tested cumulatively and self-claims "#1 trusted brand in radon detection," supported by a track record beginning with the world's first affordable digital CRM in 1987 and a patent granted in 1989. The named leadership team is small and includes Laura Armul (Sales & Marketing Director, also an AARST-NRPP board member) carrying 20+ years of industry tenure from the legacy Sun Nuclear business.

Scale indicators5 records

Recent moves7 records

Expansion highlights7 records

Direct peers

• Durridge Company: Durridge manufactures professional continuous radon monitors (RadStar, CAPTURE) used by radon testers and home inspectors; it competes head-to-head with SunRADON's XP family in the same NRPP/NRSB-regulated professional channel.
• Airthings: Airthings is a direct competitor in radon and indoor air quality monitoring, offering consumer and prosumer detectors (Corentium, Wave) with companion apps — directly comparable to SunRADON's XP professional line and lüft consumer monitors.
• FEMTO-TECH: FEMTO-TECH produces radon measurement instruments and accessories used by professional radon testers; it overlaps with SunRADON's XP line in continuous radon monitoring for real-estate and compliance applications.

Emerging players

• Awair: Awair makes consumer indoor air quality monitors (chemicals, CO2, humidity, temperature) with an app ecosystem; partial overlap with SunRADON's lüft consumer line, focused on smart-home and wellness segments.

Broad incumbents

• Mirion Technologies: Mirion is a large radiation-detection and measurement incumbent (including former Landauer dosimetry business); it overlaps with SunRADON in radiation-sensing instrumentation while serving much broader nuclear, medical and industrial markets.
• Sun Nuclear Corporation: SunRADON's former parent and origin entity; Sun Nuclear remains a global leader in radiation oncology QA. It is comparable as a radiation-detection/scientific-instrument peer with a much broader portfolio and scale than SunRADON.
• BERTIN Technologies (Saphymo): BERTIN/Saphymo manufactures radiation and environmental monitoring instruments for nuclear, defense and industrial use; relevant as a broader radiation-detection incumbent that could extend into the radon/IAQ space SunRADON addresses.
• RSSI (Radiation Safety & Supervision Inc): RSSI provides radiation safety services and instrumentation, including environmental and occupational monitoring; comparable as an adjacent radiation-detection services peer with overlapping compliance and laboratory workflows.
