(131)I is widely used in Latin America and Caribbean Region in the field of nuclear medicine and has been recognised as one of the main sources of potential intake of radionuclides by the staff. The In Vivo Monitoring laboratory of the Institute for Radiation Protection and Dosimetry (IRD-CNEN-Brazil) organised three intercomparison exercises (2005, 2009 and 2013) in the scope of IAEA technical cooperation projects RLA9049 and RLA9066 aimed to disseminate and harmonise the technique for measuring (131)I in the human thyroid. The number of participants in Latin America increased from 9 to 20 institutions from 7 and 13 countries, respectively, over the last 10 y. The participants have improved significantly their ability on the in vivo measurement technique. In the 2013 round all laboratories which reported results presented performances in an acceptable range according to the ISO criteria indicating the benefit of such exercises in the region.
碘-131在拉丁美洲和加勒比地区的核医学领域被广泛使用，并且已被认定为工作人员潜在摄入放射性核素的主要来源之一。巴西国家核能委员会辐射防护与剂量测定研究所的体内监测实验室在国际原子能机构技术合作项目RLA9049和RLA9066范围内组织了三次比对活动（2005年、2009年和2013年），旨在推广和统一人体甲状腺中碘-131的测量技术。在过去10年中，拉丁美洲的参与机构数量分别从7个国家的9个增加到13个国家的20个。参与者在体内测量技术方面的能力有了显著提高。在2013年的比对活动中，所有报告结果的实验室的表现均在符合ISO标准的可接受范围内，表明此类活动对该地区有益。
