 In Mexico and Uruguay, medical staff have been trained in the comprehensive care of children with cancer. In Bolivia, isotopic techniques are helping to preserve water supplies. Representatives from 19 Latin American and Caribbean countries were at the IAA's headquarters in Vienna to participate in the annual meeting of parties to ARCAL, a cooperation agreement to promote the peaceful use of nuclear techniques in the region. Since it was signed in 1984, the agreement has helped countries in the region tackle issues related to human health, food safety, energy, and the environment. The National Organization of Atomic Energy and ARCAL have developed, for over 30 years, 163 projects. It is very important that the use of nuclear technology has been benefited with a team and a human resource strengthening that has allowed a region of the country to be free, for example, of the Mediterranean Mosque. During the meeting, new projects were selected. For example, nuclear techniques will now help improve the safety of seafood products in the region. From Vienna, Austria, this is Alejandra Silva reporting for the IAA.
