BAQ

What BAQ does

BAQ Sàrl (trading as BAQ Engineering) is a privately held Swiss CleanTech firm founded in 2019 in Le Grand-Saconnex, Geneva, as a spin-off from CERN. The company develops sensors and air purification systems for the detection and mitigation of airborne radioactive particulate matter — most notably the RaDoM (Radon Dose Monitor) — and delivers specialized consulting in nuclear engineering, dosimetry, and radioprotection. Its underlying technology stack combines physics-based hardware (radiation sensors, filtration systems) with Monte Carlo radiation-transport simulation codes (MCNP 6.3, GEANT, SuperMC) and nuclear risk/dose assessment software (Genii-Frames, Erica 2.0) for applications including nuclear decommissioning, radon mitigation, and workplace radiation safety.

BAQ generates revenue through a mix of professional services (nuclear engineering and radioprotection consulting, radon risk assessment, indoor air quality assessments) and hardware sales (proprietary RaDoM instrumentation, the in-development Airborne Radioactive Particulate Dosimetry and Mitigation System, and resold AtmosAir air purification products). The go-to-market is direct, sales-led, and relationship-based, with named enterprise and government clients including SOGIN (nuclear decommissioning), Health Canada, CNRS, ETS Engineering, and San Cataldo Hospital in Italy. The company serves a vertical mix of nuclear industry, healthcare facilities, industrial manufacturing (stone/metal cutting), and commercial buildings. Pricing is quote-based and not publicly disclosed.

Since 2021 BAQ has broadened its scope beyond ionizing radiation into general indoor air quality (mould, viruses, bacteria, odours), and in 2024 opened a wholly-owned Italian subsidiary in Villa d'Almè (Bergamo) and obtained ISO 9001:2015 certification for nuclear engineering and R&D services. R&D is supported by a 2023 Innosuisse Innovation Grant and ongoing collaboration with HEPIA's Type B nuclear physics laboratory. The firm remains small (1-10 employees) with two co-founders in the leadership roles (CEO Alessandro Curioni, PhD Columbia; CTO Stefano Romano, ex-CERN), and has not disclosed any equity funding.

Core offering

BAQ is a CERN spin-off that develops sensors and air purification systems for real-time detection and mitigation of airborne radioactive particulate matter, radon gas, and indoor air quality hazards. Its offerings include the RaDoM radon-monitoring instrument, airborne radioactive particulate detection and purification systems, and consulting services in nuclear engineering, radioprotection, dosimetry, and radon risk assessment for nuclear facilities, hospitals, and industrial clients.

Product overview

BAQ is a CERN spin-off founded in 2019 offering a portfolio of radiation detection and air quality products alongside specialized consulting services. The core product line is anchored by the RaDoM (Radon Dose Monitor) — an innovative radon-monitoring instrument developed at CERN — and complementary air purification systems designed for environments with radioactive particulate, including radon mitigation. The company also develops an R&D-focused airborne radioactive particulate dosimetry and mitigation system. On the services side, BAQ provides nuclear engineering and radioprotection consulting (including Monte Carlo simulation, dose assessment, and radiation protection design) and indoor air quality assessment and purification services, carrying the AtmosAir product catalogue as a resale add-on. The portfolio forms a unified offering where hardware instruments, purification systems, and consulting services address the full spectrum from measurement to mitigation of radiation and air quality hazards.

Emerging players

• Airthings: Norwegian developer of consumer and prosumer radon and indoor air quality sensors. Comparable radon-monitoring technology focus, though BAQ targets enterprise/nuclear segments versus Airthings' consumer-led approach.

Direct peers

• Mirion Technologies: Leading global provider of radiation detection, measurement, and monitoring solutions for nuclear, medical, and industrial applications. Directly comparable to BAQ's radiation dosimetry and detection business across similar customer segments.
• Saphymo: French manufacturer of radiation monitoring systems and dosimetry equipment for the nuclear industry and homeland security. Comparable technology stack and European nuclear customer base to BAQ.
• Bertin Instruments (Exosens): European manufacturer of radiation detection and monitoring instruments for nuclear, defense, and environmental applications. Comparable product portfolio and CERN-adjacent scientific instrument heritage.
• Tracerco (Johnson Matthey): Provider of radiation monitoring, dose assessment, and decontamination services for nuclear, oil & gas, and industrial sectors. Overlapping consulting and instrumentation offering to nuclear and industrial customers.
• Radonova Laboratories: Specialized provider of radon measurement services and detection equipment for buildings and workplaces. Closely comparable to BAQ's radon-focused RaDoM product line and indoor air quality consulting.

Others
