Cobalt's Radioactive Secret Fuels EV Boom

The Democratic Republic of Congo, a major cobalt producer powering the electric vehicle revolution, is grappling with significant uranium contamination in its exports. This natural occurrence in the copper belt region, historically known for uranium mining, poses serious health risks to mine workers and raises international security concerns about the potential diversion of nuclear material.

Recent research indicates that the uranium mingled with Congo's cobalt exports between 2000 and 2024 is substantial, with amounts equivalent to fueling a large nuclear reactor for a decade. Congolese officials are seeking international funding to install radiation detectors at border crossings to monitor truck shipments, aiming to mitigate proliferation risks and protect both national and global security.

Several major mining operations have encountered uranium contamination issues, with some facing export halts until processing systems were adapted to remove the radioactive material. While some companies claim compliance with regulatory limits, questions persist about the ultimate fate of the uranium, particularly concerning its potential extraction in processing countries like China, which has a growing nuclear program.

Immediate challenges include monitoring shipments before they leave the DR Congo and addressing the health impacts on local populations. The cost for implementing comprehensive monitoring systems across the vast country is substantial, with authorities discussing potential funding with international partners to enhance security and transparency in the cobalt supply chain.
