Continued Incidents Raise Concerns Over Nuclear Security, Says UN

Transportation of radioactive materials remains one of most vulnerable areas.

There were almost 150 incidents of illegal or unauthorised activity involving nuclear and other radioactive material reported last year, according to the International Atomic Energy Agency’s (IAEA) monitoring database.

New data reveals that while the overall number remains consistent with previous years, the continued incidents of trafficking and radioactive contamination cases raises concerns over nuclear security, the United Nations said on its website.

Three of the reported cases were directly linked to trafficking or malicious intent, while in 21 incidents, authorities could not determine whether criminal activity was involved.

Most incidents did not involve organised crime, but experts warn that even a single case of nuclear material falling into the wrong hands could pose serious global risks.

A troubling trend in 2024 was the rise in contaminated industrial materials, such as used pipes and metal parts that unknowingly entered supply chains.

“This indicates the challenge for some countries to prevent the unauthorised disposal of radioactive sources, and at the same time, it confirms the efficiency of the detection infrastructure,” said Elena Buglova, director of the IAEA’s division of nuclear security.

The transportation of radioactive materials remains one of the most vulnerable areas of nuclear security. Over the past decade, 65% of all reported thefts have occurred while materials were in transit.

Nuclear and radioactive substances are regularly transported for use in medicine, industry and scientific research, making them a potential target for theft. With so many different handlers involved during shipping, security gaps persist.

Experts emphasise the need for stronger safety measures while goods are on the move to prevent radioactive material from being lost or stolen.

Enhanced international cooperation is also essential to ensure proper security along supply chains.
