Philippine authorities have successfully relocated 23 containers of radioactive zinc dust to a secure onshore facility after months of diplomatic and environmental complications. The shipment, originally destined for Indonesia, became the center of an international incident when Indonesian officials detected traces of radioactive Caesium-137 and promptly returned the hazardous materials to their point of origin.
The containers arrived in Manila Bay aboard the MV Hansa Augsburg in late September 2025 following Indonesia’s rejection. The Southeast Asian nation had implemented stringent measures against scrap iron and steel imports amid growing concerns about radioactive contamination in food products. After extensive negotiations and planning, Philippine Nuclear Research Institute (PNRI) director Carlo Arcilla confirmed the containers were safely offloaded at Manila’s port on January 11, 2026.
Arcilla characterized the situation as a ‘solvable problem’ with relatively low contamination levels. ‘The radiation becomes background just one meter away from the container,’ he stated, noting that the ship’s crew had tested negative for radiation exposure. The current temporary storage location outside Metro Manila will soon be replaced by a more permanent solution at the Subic Bay military facility, where World War II-era ammunition bunkers provide adequate containment infrastructure.
The incident has exposed significant challenges in international hazardous material transport protocols. China’s Cosco Shipping Lines, the vessel operator, reportedly suffered substantial financial losses during the extended stalemate. Arcilla suggested the company fell victim to ‘irrational fear of radiation’ compounded by administrative delays in finding an appropriate storage solution.
Environmental organizations including Greenpeace Philippines have expressed concerns about the long-term risks associated with Caesium-137 exposure. Campaigner Jefferson Chua warned that even low-level contamination could pose cancer risks and persistent environmental damage. The radioactive isotope, commonly used in industrial and medical applications, requires specialized handling procedures that have complicated resolution efforts.
Neither the exporting companies—Zannwann International Trading Corp and Steel Asia—nor Cosco Shipping Lines immediately responded to requests for comment regarding the ongoing situation and responsibility for the radioactive materials.
