The International Atomic Energy Agency’s Environment Laboratories are the central coordinator of the ALMERA network's activities.

To facilitate interactions between the ALMERA laboratories, the network is subdivided into the following regional groups:

• Africa
• Europe
• Middle East
• Asia Pacific
• North and Latin America

Each regional group is coordinated by an ALMERA regional coordinating centre. The current coordinating centres are:

• the Egyptian Nuclear And Radiological Regulatory Authority (ENRRA) for Africa,
• the Karlsruhe Institute of Technology, Germany for Europe;
• the Atomic Energy Commission of Syria (AECS) for Middle East.
• the Australian Nuclear Science and Technology Organization (ANSTO, Australia) for the Asia-Pacific region, and,
• the Canadian Nuclear Safety Commission for the North and Latin America region.
