Global Radiation Monitoring Market Outlook, 2031

The global radiation monitoring industry covers instruments, systems and services that detect, measure and record ionising radiation, including gamma rays, X-rays, beta and alpha particles and neutrons, to protect workers, patients, the public and the environment and to secure nuclear and radioactive materials. Products include personal dosimeters worn by workers, such as thermoluminescent, optically stimulated luminescence and electronic dosimeters; area and process radiation monitors installed in nuclear power plants, research reactors, hospitals and laboratories; environmental radiation monitoring stations and networks that measure background radiation and detect releases; surface contamination monitors and portal monitors for personnel and vehicles; handheld survey meters and radioisotope identification devices; radiation portal monitors at borders and ports to detect smuggled materials; spectroscopy systems; and dosimetry services that read badges and maintain dose records. Detector technologies include Geiger-Müller tubes, ionisation chambers, scintillators, semiconductor detectors such as high-purity germanium and cadmium zinc telluride, and neutron detectors. Leading companies include Mirion Technologies, Thermo Fisher Scientific, Landauer within Fortive, Fuji Electric, Hitachi, Ludlum Measurements, Polimaster, Berthold Technologies, Kromek, Rapiscan, Smiths Detection, Canberra within Mirion, Bertin Technologies, RadComm, Arrow-Tech and Chinese and Russian suppliers.

Radiation monitoring demand is driven by nuclear power, medicine, homeland security and environmental protection, and several trends have strengthened it. A renewed global interest in nuclear energy, driven by energy security, climate goals and electricity demand from data centres, has led to reactor life extensions, restarts and new builds. More than 30 countries pledged at COP28 in 2023 to triple nuclear capacity by 2050, the United States issued executive orders in May 2025 to accelerate reactor licensing and expand nuclear capacity, and technology companies such as Microsoft, Google, Amazon and Meta signed agreements for nuclear power, including the planned restart of Three Mile Island Unit 1 and support for small modular reactors. China, India and others continue large reactor programmes. Each reactor and SMR requires extensive radiation monitoring systems. Mirion, the largest specialist supplier, acquired Certrec in July 2025 and Paragon Energy Solutions for about USD 585 million in December 2025 to strengthen its position in US nuclear power and SMRs. Events have also highlighted monitoring needs: Japan began releasing treated water from Fukushima Daiichi in August 2023 under IAEA oversight with extensive monitoring, and fighting around the Zaporizhzhia nuclear plant in Ukraine since 2022 has raised concerns about radiation safety. In medicine, growth in diagnostic imaging, interventional radiology, radiotherapy and radiopharmaceuticals such as Pluvicto increases staff and patient dosimetry needs, and decommissioning of old reactors in Europe, Japan and the United States requires monitoring of waste and sites.

Market Dynamics

Market Drivers
• Nuclear Power Expansion, Life Extensions and SMRs:Governments and utilities are extending the lives of existing reactors, restarting closed plants, building new large reactors in China, India, Turkey, Egypt, Bangladesh, the UAE and elsewhere, and developing small modular reactors in the United States, Canada, the UK and Europe. Technology companies' demand for firm clean power for data centres has accelerated interest. Each project requires radiation monitoring systems for reactor safety, worker protection and environmental monitoring, and digital upgrades of older plants create replacement demand.
• Medical Use of Radiation and Homeland Security:Growth in CT scans, interventional cardiology, nuclear medicine, radiotherapy and radioligand therapies increases the number of workers and patients requiring dose monitoring, and regulations require dosimetry for staff. Governments invest in radiation detection at borders, ports, airports and major events to prevent nuclear and radiological terrorism, and military and emergency responders need portable detectors. Heightened geopolitical tensions and conflict near nuclear facilities have increased emergency preparedness spending.

Market Challenges
• Regulatory Complexity and Long Procurement Cycles:Radiation monitoring systems for nuclear facilities must meet strict safety and quality standards and be qualified for harsh conditions, making development costly and procurement slow. Nuclear projects often face delays and cost overruns that postpone equipment orders. Export controls and national security rules restrict some sales, and sanctions on Russia have disrupted supply chains in the nuclear sector.
• Supply Chain Constraints and Skilled Workforce Shortages:Some detector materials, such as helium-3 for neutron detection and high-purity germanium, have limited supply, and specialised electronics face supply chain pressures. The nuclear and radiation protection workforce is ageing, and shortages of health physicists and technicians limit the capacity to deploy and maintain systems. Public concerns about nuclear power vary by country, creating political uncertainty for long-term demand.



Market Trends
• Digital, Networked and Real-Time Monitoring:Radiation monitoring is moving from periodic badge readings and standalone instruments to networked electronic dosimeters and sensors that provide real-time dose data, alarms and remote supervision. Cloud platforms and data analytics support dose management across hospitals, plants and fleets of devices. Nuclear plants are upgrading analogue monitoring systems to digital systems, and environmental networks share data publicly, as in Japan and Europe.
• Advanced Detectors, Drones and Robotics:New detector materials, such as cadmium zinc telluride, advanced scintillators and compact neutron detectors, improve sensitivity, energy resolution and portability. Drones and robots equipped with radiation sensors are used to survey contaminated areas, decommissioning sites and emergency zones, as at Fukushima and Chernobyl. Wearable and smartphone-linked detectors expand access, and AI helps identify isotopes and reduce false alarms at border portals.

Segment Analysis

Personal dosimeters account for the largest number of radiation monitoring devices in use, while area and process monitoring systems and environmental monitoring generate significant value. Personal dosimeters are worn by radiation workers in hospitals, nuclear plants, industry, research and the military to measure individual exposure, and they include passive thermoluminescent and optically stimulated luminescence badges read periodically by dosimetry services, and electronic personal dosimeters that display dose and alarm in real time. Area radiation monitors measure radiation levels in rooms and facilities, while process radiation monitors measure radioactivity in effluents, coolant, ventilation stacks and process streams in nuclear plants. Environmental radiation monitoring systems, including fixed stations, air samplers and laboratory analysis, track radiation in air, water, soil and food around nuclear sites and across national networks. Surface contamination monitors, hand and foot monitors, whole-body monitors and portal monitors check personnel and equipment leaving controlled areas. Handheld survey meters and radioisotope identification devices are used by health physicists, first responders and security personnel. Radiation portal monitors at borders and ports screen vehicles, containers and people. Spectroscopy systems identify radionuclides. Dosimetry services, including badge reading and dose record management, form a recurring revenue segment.

Gas-filled detectors and scintillators are the most widely used radiation detection technologies, while semiconductor detectors are growing because of their precision and compact size. Gas-filled detectors, including Geiger-Müller counters, ionisation chambers and proportional counters, are widely used in survey meters, area monitors and contamination monitors because they are rugged and reliable. Scintillation detectors, using materials such as sodium iodide, cesium iodide, plastic scintillators and newer materials such as lanthanum bromide, convert radiation into light pulses and are used in portal monitors, spectroscopy and environmental monitoring. Semiconductor detectors, including high-purity germanium for high-resolution spectroscopy, silicon detectors and cadmium zinc telluride, offer precise energy measurement and compact size and are used in electronic dosimeters, isotope identification and medical applications. Thermoluminescent and optically stimulated luminescence materials are used in passive dosimeters. Neutron detectors, traditionally based on helium-3 and increasingly on alternatives such as boron and lithium-based materials, are used in nuclear safeguards and security. Solid-state and fibre-optic sensors are emerging. The choice of technology depends on the radiation type, sensitivity, energy resolution, cost and environmental conditions required.

Nuclear power and fuel cycle facilities and healthcare are the largest end users of radiation monitoring, while homeland security, industrial and research users form major segments. Nuclear power plants and fuel cycle facilities, including uranium mining and enrichment, fuel fabrication, reprocessing, waste storage and decommissioning sites, require comprehensive radiation monitoring systems for reactor safety, worker protection and environmental protection, and they generate high-value, long-term contracts. Healthcare, including hospitals, imaging centres, radiotherapy departments, nuclear medicine and radiopharmacies, is the largest user of personal dosimetry, monitoring staff exposed during imaging and interventional procedures, and radiopharmaceutical growth increases monitoring needs. Homeland security and defence users, including border agencies, customs, ports, military forces and emergency responders, use portal monitors, handheld identifiers and personal detectors. Industrial users, including industrial radiography, oil and gas well logging, mining, food irradiation and manufacturing, monitor workers and sources. Research laboratories, universities, particle accelerators and national laboratories use monitoring for experiments and facilities. Environmental agencies operate national radiation monitoring networks. Space agencies monitor radiation for astronauts and electronics.

Hardware accounts for the largest share of radiation monitoring revenue, while dosimetry services, software and maintenance provide growing recurring revenue. Hardware, including detectors, instruments, monitors, portals and integrated systems, accounts for the largest share of revenue, with large systems for nuclear plants and border security representing major contracts. Dosimetry services, in which companies such as Mirion, Landauer and national services supply badges, read them and maintain regulatory dose records for hospitals and industry, provide recurring subscription revenue. Software and data management platforms record dose histories, manage instrument fleets, analyse environmental data and integrate with plant control systems. Calibration, maintenance and repair services keep instruments accurate and compliant with standards, and they are required periodically. Training and consulting services support radiation protection programmes. Installation and system integration services are important for nuclear new builds and plant upgrades. Rental of instruments supports outages, decommissioning projects and emergencies. Upgrade and replacement of ageing analogue systems in nuclear plants is a significant opportunity.
