Traceability in Nuclear Medicine Service (NMS) measurements was checked by the Institute of Radioprotection and Dosimetry (IRD) through the Institute of Energy and Nuclear Research (IPEN). In 2016, IRD ran an intercomparison program and invited Brazilian NMS authorized to administer I to patients. Sources of I were distributed to 33 NMSs. Three other sources from the same solution were sent to IRD, after measurement at IPEN. These sources were calibrated in the IRD reference system. A correction factor of 1.013 was obtained. Ninety percent of the NMS comparisons results are within ±10% of the National Laboratory of Metrology of Ionizing Radiation (LNMRI) value, the Brazilian legal requirement.
放射防护与剂量测定研究所（IRD）通过能源与核研究机构（IPEN）对核医学服务（NMS）测量的可追溯性进行了检查。2016年，IRD开展了一项比对计划，并邀请巴西经授权为患者施用碘-131的核医学服务机构参与。碘-131源被分发给了33家核医学服务机构。在IPEN进行测量后，同一溶液中的另外三个源被送往IRD。这些源在IRD参考系统中进行了校准。得到的校正因子为1.013。90%的核医学服务机构比对结果在巴西法定要求——电离辐射计量国家实验室（LNMRI）值的±10%范围内。
