On August 19, 2025, the U.S. Food and Drug Administration (FDA) detected Cesium-137, a hazardous radioactive isotope, in frozen shrimp processed at an Indonesian facility. The discovery triggered immediate international concern over the safety of Indonesian exports and exposed a hidden radiation pollution crisis within the nation’s industrial zones.
Indonesian authorities swiftly launched a comprehensive environmental audit of the processing plant. Following a multi-agency traceability investigation, the contamination source was pinpointed: Peter Metal Technology, a local steel smelting factory. During scrap steel smelting, industrial waste containing Cesium-137 had inadvertently mixed with raw materials. Radioactive pollutants from the smelting process spread through the industrial park’s shared public utilities to numerous surrounding enterprises, affecting food processing, light manufacturing, and other sectors.
To halt further contamination and rebuild international market confidence, the Indonesian government urgently mandated the establishment of a robust radioactive contamination detection system and initiated cleanup operations, targeting complete decontamination of affected zones by the end of 2025.
Addressing Indonesia’s critical gap in radiological protection capabilities, Shanghai-based Ergodi, a specialist in radiation monitoring, rapidly responded. Leveraging precise scenario assessment and deep technical expertise, the company delivered a customized monitoring solution that earned high recognition from local distribution partners.
At the core of the strategy is Ergodi’s proprietary RJ11 Vehicle Radiation Portal Monitor (RPM)—a system which is primarily used to monitor if there are radioactive materials carried by trucks, container vehicles, trains, and if other vehicles contain excessive radioactive substances.The RJ11 employs large-volume plastic scintillators paired with low-noise photomultiplier tubes, achieving exceptional online detection sensitivity of 20,000 cps per μSv/h for Cesium-137. The system enables rapid, accurate screening of vehicles for radioactive contaminants, providing 24/7 real-time automated monitoring to sever contamination pathways at the logistics level and safeguard personnel and environmental safety.
Recognizing the operational priorities of Indonesia’s small and medium-sized enterprises—namely ease of use and technical reliability—Ergodi tailored a turnkey solution built around the RJ11 RPM‘s inherent stability and flexible configuration options. The system requires minimal training for rapid deployment, seamlessly aligning with the local “phased resumption + continuous spot-check” remediation approach. This ensures comprehensive, high-precision radiological monitoring across park enterprises without disrupting production efficiency.
Ergodi’s swift support in Indonesia’s nuclear contamination crisis represents not only a rapid response to international nuclear safety emergency needs but also a vivid demonstration of China’s radiation monitoring technology advancing onto the global stage. With mature, reliable equipment and scenario-specific customization, Ergodi is helping Indonesia build a comprehensive radiation detection system, while fortifying a critical line of defense for radioactive safety across the global supply chain using professional-grade capabilities.
