Radosys

What Radosys does

Radosys, Ltd. is a Budapest, Hungary-based private company founded in 1997 that develops and manufactures dosimeter systems based on PADC (polyallyl diglycol carbonate, equivalent to CR-39) etched-track technology for radon, thoron, and neutron radiation detection. Its integrated product platform comprises automated nuclear track readers (EcoReader, NanoReader, Radometer 2000, Radometer DH), etching units (NanoBath, RadoBath), a portfolio of PADC detector types (RSKS, RSGS, RSFV/RSFW, RADUET, RSNS), proprietary image-analysis software, and a MN-series biodosimetry system for radiation dose estimation via micronucleus counting. All systems carry full ISO-11665 compatibility, and the company holds more than 110 installations across roughly 20 countries in Europe, Japan, North America, and Asia.

The company monetizes primarily through one-time hardware sales of complete dosimeter systems, detectors, etching units, and accessories, supplemented by software licenses and service/support including bundled calibration data. Pricing is structured as unit pricing across tiered configurations ranging from home-lab (EcoReader/NanoReader) to high-volume professional radioprotection laboratories (Radometer 2000/DH for 500+ or 5,000+ detectors per year). Go-to-market is direct enterprise field sales executed through three wholly-owned regional entities: Radosys, Ltd. in Budapest (covering Europe, Asia, Australia), Radosys Americas LLC in Branford, CT (USA/Canada), and Radosys Atlantic Lda in Coimbra, Portugal (regional sales/support). Customer segments are primarily governmental radiation-protection organizations, university research departments, and private radon test service providers.

The business model relies on a vertically integrated hardware-software-consumable stack: PADC detector chips are explicitly compatible only with Radosys systems, which embeds the company into the recurring consumable cycle of its installed base and creates ecosystem-level switching costs for laboratories. Strategic partnerships (notably the NIRS Japan collaboration that produced the RADUET radon-thoron detector) and ISO-11665 certification serve as the main mechanisms for product differentiation and market access.

Core offering

Radosys develops and manufactures complete dosimetry systems based on PADC etched-track detector technology for the measurement of radon, thoron, and neutron radiation. Its offering combines disposable solid-state detector chips with automated optical readers, chemical etching units, and image-analysis software, packaged as turnkey measurement chains for environmental radiation monitoring.

Product overview

Radosys offers an integrated dosimetry system based on PADC etched-track technology for radon, thoron, and neutron detection. The product portfolio centers on nuclear track reader instruments (EcoReader, NanoReader, Radometer 2000, Radometer DH) that process PADC/CR-39 detector chips through etching units (NanoBath, RadoBath). The system supports multiple detector types: RSKS (standard), RSGS (large area), RSFV/RSFW (wide range/double chamber), RADUET (radon-thoron combined), and RSNS (neutron). Specialized image analysis software enables automated track counting and micronucleus analysis for biodosimetry applications. All components are ISO-11665 compatible and designed for applications ranging from home lab use to professional radiation protection laboratories.

Broad incumbents

• Tracerco (Johnson Matthey): Tracerco, part of Johnson Matthey, provides radiation monitoring, nucleonic measurement, and inspection services to oil & gas, petrochemical, and nuclear industries. Comparable because it sells radiation detection instrumentation to industrial and governmental safety customers.
• Mirion Technologies (Landauer): Mirion owns the legacy Landauer dosimetry franchise and offers a broad portfolio of radiation measurement products including passive radon detectors, electronic dosimeters, and biodosimetry. Comparable because it addresses the same radiation protection and radon monitoring buyers, though it operates at much greater scale and breadth.
• Sun Nuclear (Mirion): Sun Nuclear, now part of Mirion, is a leading provider of radiation detection and quality assurance solutions used in radiation therapy, medical imaging, and radiation protection. Comparable as a broader radiation dosimetry instrumentation competitor with overlapping customer segments.
• Thermo Fisher Scientific (Radiation Measurement): Thermo Fisher supplies radiation detection and measurement instruments including portable and laboratory radiation monitors, dosimetry systems, and nuclear measurement solutions. Comparable as a broad incumbent serving the same radiation protection and nuclear-industry buyer base.

Direct peers

• SARAD GmbH: SARAD manufactures radon and radiation measurement instruments including both active (continuous electronic) and passive radon monitors. Comparable because it targets the same radon-testing service provider and government radiation protection customer base with overlapping measurement methods.
• Radonova: Radonova (formerly Landauer Nordic) sells radon measurement services and devices using PADC/CR-39 track-etch detectors, with a strong presence in European radiation protection markets. Direct competitor to Radosys in the same passive etched-track radon dosimetry product category.
• Durridge Company: Durridge makes the RAD7 and related continuous electronic radon monitors widely used by radon test professionals and researchers. Competes with Radosys on radon measurement for the same end customers, but uses an electronic rather than etched-track detection method.

Regional players

• Bertin Instruments: Bertin Instruments (part of the Onet Technologies group) supplies radiation and environmental monitoring instruments across European markets. Comparable because it sells radiation measurement and detection equipment to similar European government and research customers, though with a wider environmental monitoring portfolio.
