May 2025 Newswire

Editor’s Note

May 2025 was a “plumbing and infrastructure” month for radiation detection: less about spectacular new threats, more about how we maintain, train, and modernize the systems that are already in the field. From handheld RIDs and data-driven algorithms for radiation portal monitors, to multi-country preparedness exercises and evolving scrap-metal policies, the month’s stories point to a more integrated, operationally mature detector ecosystem. This Newswire focuses on non-medical radiation detection across border security, safeguards, technology, scrap/recycling, and policy.

Border Security & Customs

Support for Ukrainian border RPMs highlighted in U.S. oversight reportingA U.S. Government Accountability Office (GAO) report on Department of Energy programmes (released in June but describing activities through May 2025) notes ongoing efforts to sustain and “salvage” radiation portal monitors deployed for Ukrainian border guards, including the deployment of RPMs at new crossing points and procurement of handheld and mobile radiation detection units for emergency services and police. NRC officials are reported to have given an update on these RPM efforts in May 2025. GAO – DOE Could Better Assess Fraud Risks and Formalize Its Oversight of Ukraine Assistance

Why it matters: For the RPM industry, this confirms that war-adjacent border regions remain a strategic deployment area, and that long-term sustainment (spares, repair, calibration) is now part of the border-security conversation, not just initial installation.

LINEV highlights border X-ray scanners with integrated radiation detectionLINEV Systems showcased its border X-ray scanner capabilities in a 6 May 2025 article, emphasising the combination of high-throughput cargo imaging with embedded radiation detectors and advanced analytics. The piece focuses on securing high-volume trade lanes while maintaining flow, positioning integrated X-ray plus radiation detection as a core tool for customs risk management at modern borders. LINEV Systems – “Securing Borders with LINEV’s Border X-ray Scanner While Facilitating Trillions in Trade”

Why it matters: Border agencies increasingly want single-lane systems that combine imaging, radiation detection, and analytics into one managed asset. This reinforces the trend away from standalone RPMs toward integrated inspection platforms.

Nuclear Security & Safeguards

• IAEA runs advanced handheld detection training in ViennaFrom 5–9 May 2025, the IAEA hosted an Advanced Training Course on the Use and Maintenance of Hand-Held Radiation Detection Equipment in Vienna. The course targeted frontline users and technical staff, focusing on operational use, maintenance, troubleshooting and calibration of handheld detectors used for illicit-trafficking detection and emergency response. The event forms part of the IAEA’s broader nuclear security training portfolio.  Why it matters: Many national programmes have sufficient detector hardware but weaker maintenance and lifecycle management. The IAEA’s focus on use and maintenance underlines that reliability and uptime are becoming key performance indicators for detection systems.

NNSA’s Cobalt Magnet 25 exercise showcases large-scale radiological monitoringThe U.S. National Nuclear Security Administration (NNSA) published a 13 May 2025 article summarising Cobalt Magnet 25—a major nuclear/radiological incident exercise involving more than 3,000 participants from over 70 agencies in Michigan. The exercise scenario was a severe nuclear power plant accident, with activities including field teams using radiological detection instruments, low-flying aircraft for aerial measurements, and multi-agency coordination of data and decision-making. NNSA – “NNSA partners with over 70 agencies for successful radiological management exercise”

Why it matters: Large national exercises like Cobalt Magnet validate not only detector performance, but also the workflows for moving measurement data into actionable situational awareness—an increasingly important requirement for vendors supplying networks of instruments, not just standalone devices.

EU CBRN CoE strengthens detection and response capacity in Sierra Leone and LiberiaOn 13 May 2025, the EU CBRN Risk Mitigation Centres of Excellence reported on capacity-building exercises in Sierra Leone and Liberia. The February 2025 activities, documented in a May news article, combined needs assessments, table-top exercises, and live drills focused on operating CBRN equipment and coordinating agencies during radiological and nuclear scenarios. Equipment training and “real-life” drills were highlighted as essential to ensuring that detection assets, which are often used infrequently, remain functional and effective. EU CBRN CoE – “Sierra Leone and Liberia step up efforts to strengthen CBRN preparedness through EU-supported exercises”

Why it matters: This shows how donor-funded programmes are moving beyond equipment donations toward structured, scenario-driven training that treats radiation detection as part of a broader emergency-management system.

Technology & R&D

• New algorithm for low-intensity gamma source detection in RPMsNuclear Instruments and Methods in Physics Research A published an article (available online 21 May 2025) describing a “fast and reliable algorithm for the detection of low-intensity gamma-ray sources in radiation portal monitoring”. The work proposes improved statistical treatment of background and signal to detect weak sources in transit, where count statistics are limited and shielding may be present.  Why it matters: As RPM fleets age and are exposed to more complex cargo mixes, software upgrades can materially extend performance without replacing hardware. Algorithms that better handle low-count, low-contrast scenarios are directly relevant to ports looking to improve detection probability without increasing nuisance alarms.
• AI-aided nuclide identification for portable spectrometersComplementing the RPM work, a May-2025-dated pre-proof in Nuclear Science and Techniques describes a low-power, multiple-nuclide identification algorithm for portable gamma spectrometers, aimed at embedded deployment in field instruments. The method uses optimised feature extraction and model structures to perform real-time nuclide ID on constrained hardware.  Why it matters: This fits a broader trend toward “smarter at the edge” detectors, where nuclide ID and anomaly detection increasingly run on the device itself, reducing dependence on backend servers and improving responsiveness for patrols and first responders.

Nanostructured scintillators for special nuclear material detectionA 29 May 2025 CORDIS feature summarised EU-funded work on tapered ZnO nano-array scintillators optimised for neutron detection, aimed at locating special nuclear materials like enriched uranium and plutonium. The article highlights compact, low-cost devices suitable for mobile detection units and real-time monitoring at border control points, cargo inspection facilities and in non-proliferation applications. CORDIS – “Nanomaterials offer a safer, faster way to develop devices for use in nuclear threat detections”

  Why it matters: Post-³He, neutron-sensitive materials that can be ruggedised and mass-produced are still a bottleneck. Work like this indicates a steady pipeline of candidate technologies that could eventually feed into next-generation RPMs and mobile systems.

Symetrica launches VeriFinder™ S100 handheld RIDOn 15 May 2025, Symetrica announced the VeriFinder™ S100, describing it as a “mission-oriented” handheld radionuclide identification device with up to 14 hours of continuous operation. The RID emphasises fast start-up (under 90 seconds even in high radiation fields), ergonomic low weight, onboard continuous stabilisation (minimising routine calibration), and identification of multiple threat, industrial and medical isotopes under challenging conditions. Early orders from governmental agencies with deployments expected in 2025 were noted. Symetrica – “New VeriFinder™ S100”

  Why it matters: For mobile teams and border officers, battery life, stabilisation and ease of use are often more limiting than raw resolution. The S100 is a good example of how RID vendors are competing on mission endurance and lifecycle cost, not just spectroscopy specs.

Market & Policy Signals

• Kromek broadens collaboration on fixed and portable detectorsMarket-research summaries of the radiation portal monitor and portable nuclear radiation detector markets note two notable Kromek partnerships during May 2025:These developments are reported in sector market reports rather than primary RNS releases, but they align with Kromek’s broader strategy of partnering for distribution and subsystem integration.Why it matters: For integrators and end-users, this suggests that more Kromek-based detector modules may appear “inside” third-party portal and handheld systems, which can influence lifecycle support, upgrade paths, and interoperability planning.
  • a collaboration with RADOS Technology to co-develop next-generation fixed radiation portal monitors for border-security applications; and
  • a multi-year partnership with Seiko Instruments to co-develop and commercialise compact portable gamma detectors for border security, combining Kromek spectroscopy with Seiko’s miniaturisation and power-management capabilities.  
• RPM market outlook underscores border-security demandA June 2025 RPM market report (looking forward but summarising 2025 conditions) estimates the fixed RPM market at around $2 billion in 2025 with projected ~8% CAGR to 2033, attributing growth to renewed investment in border, airport and critical-infrastructure security.  Why it matters (for a May snapshot): While outside the strict May window, this kind of forecast contextualises why May’s incremental orders, collaborations and R&D efforts are happening: RPMs remain a growth market, especially in regions facing heightened trafficking and proliferation concerns.

Kromek secures $900k in D3-series nuclear security ordersOn 28 May 2025, multiple market and RNS feeds reported that Kromek Group plc had won approximately $900,000 in new nuclear security orders for its D3-series detectors from customers in Europe and the United States, with deliveries due immediately. The orders are described as part of Kromek’s radiation and bio-detection portfolio, highlighting demand driven by heightened geopolitical risk. Reuters via TradingView – “Kromek Group Receives Two Orders For D3 Series Detectors”

  Why it matters: Although modest in absolute size, these quick-delivery orders are a useful indicator of continued operational procurement for wearable and portable detectors alongside larger framework contracts.

Scrap, Recycling & Environmental Monitoring

DOE rescinds long-standing moratorium on free release of contaminated scrap metalOn 15 May 2025, the U.S. Department of Energy published a Federal Register notice titled “Rescinded Guidance Materials”, formally rescinding two key policies: the 2000 moratorium on the free release of volumetrically contaminated metals and the suspension on the unrestricted release of scrap metal from radiation areas within DOE facilities. Subsequent DOE operating experience guidance in November 2025 discusses implementation of this change and refers back to the 15 May notice. Federal Register – “Rescinded Guidance Materials”

  Why it matters: While this is a policy move rather than a deployment, it has direct implications for how scrap-metal from DOE sites is surveyed, cleared, or kept under control. Facility operators and scrap processors should expect discussion about measurement standards, clearance levels and liability—potentially driving demand for high-sensitivity measurement systems and clear, auditable survey processes.

Radiation portal detectors halt operations at Los Alamos Eco StationOn 5 May 2025, Los Alamos County’s Eco Station (a municipal waste and recycling facility) suspended services after radiation portal detectors at the site triggered an alarm while a collection truck was unloading a residential route. According to the 9 May 2025 local report, operations were paused for the rest of the day while Environmental Services staff and radiation experts investigated the suspected radioactive material in the load. Los Alamos Reporter – “County Eco Station Services Impacted Due To May 5 Radiation Detection”

  Why it matters: This is a textbook example of portal monitors doing exactly what they are supposed to do in municipal waste streams—detect unexpected sources before they enter compaction or processing equipment. It also illustrates the operational impact: even small alarms can shut a facility for hours, which is why good alarm-handling protocols and management communication are essential.

What This Month Tells Us

• Operations and lifecycle are front and centre. Training on handheld maintenance, DOE discussions about RPM sustainment in Ukraine, and policy shifts around scrap metal all point to a maturing view of detectors as long-lived assets that need governance, not just procurement.
• Algorithms are becoming a differentiator. May saw concrete progress on algorithms for low-intensity gamma detection in RPMs and embedded nuclide identification in portable spectrometers, reinforcing that software updates can deliver significant performance gains on existing hardware fleets.
• Handheld and wearable devices keep evolving. Symetrica’s S100 launch and Kromek’s D3-series orders show continuing investment in RIDs and PRDs, particularly for border and emergency-response users who need long battery life, simple interfaces and reliable ID.
• Partnerships and integration are shaping the product landscape. Collaborations between detector manufacturers (Kromek) and system integrators (RADOS, Seiko) suggest more “mixed-heritage” systems, where core spectroscopic modules from specialised vendors are embedded in broader X-ray or portal platforms.
• Scrap and waste streams remain a sensitive frontier. The Los Alamos Eco Station incident and DOE’s scrap-metal policy shift underline that radiation detection in recycling and waste processing is not just about rare catastrophic events; it is becoming part of routine operational risk management.
• For practitioners, “plumbing” decisions are strategic. Choices about training, maintenance regimes, algorithm upgrades, and scrap-handling policies may not look glamorous, but they are increasingly where real capability and risk are decided.
