Building Expertise in Nuclear Security Response in Latin America and the Caribbean

The first IAEA regional workshop to develop nuclear security response capabilities in Latin America and the Caribbean took place in November 2025 in Goiânia, Brazil, where almost forty years ago one of the world's most serious radiological accidents occurred.

The week-long workshop provided theoretical and practical training on a coordinated multi-agency nuclear security response, addressing aspects such as the national framework, operations and communication. It was attended by nearly 30 participants from 13 countries in the region, representing a broad range of organizations with nuclear security responsibilities.

"Approaching nuclear security through a regional lens is essential," said Elena Buglova, Director of the IAEA's Division of Nuclear Security. "Helping countries strengthen their expertise to respond effectively to nuclear security events is part of the IAEA's capacity building programme, in line with the relevant nuclear security guidance recommendations."

Hosted by the Government of Brazil through the Midwest Regional Center for Nuclear Sciences (CRCN-CO) of the National Nuclear Energy Commission (CNEN), the workshop was supported by the country's Nuclear and Energy Research Institute (IPEN), which became Latin America's first IAEA Collaborating Centre for nuclear security in June 2024. Since then, IPEN has hosted four IAEA nuclear security training events and participated in several research activities related to computer security.

"Hosting this regional workshop in Goiânia holds a very special meaning for Brazil. The city's history reminds us of the importance of preparedness, coordination and transparent communication in nuclear safety and security. By bringing together professionals from across the region, this workshop strengthens our collective capacity to respond effectively to incidents involving nuclear or radioactive material," said Joana Azambuja, Head of the CNEN's Technical Cooperation Office. "It also reinforces CNEN's long-standing partnership with the IAEA and its commitment to building strong nuclear security frameworks," she added.

The workshop included a hands-on demonstration of radiation detection instruments used to support nuclear security operations and a scenario-based exercise that enabled participants to practice responding to criminal or intentional unauthorized acts involving radioactive material and to observe the range of capabilities required for an effective response. The training addressed also public communication during nuclear security events.
