• Abstract: Workers occupationally exposed to ionizing radiation (IOE) are required to be individually monitored, on a monthly basis, by External Individual Monitoring Services (SMIE). The objective of the work was to address the certification process of services offered by external individual dosimetry laboratories in Brazil with the Testing and Calibration Services Assessment Committee (CASEC) linked to CNEN's IRD, as well as associated details, with a view to education professional to understand the flow for students and schools. The methodology involved a bibliographical search for scientific articles, in addition to online open registration data platforms belonging to the bodies. Subsequently, a technical visit was carried out. The results showed that the license to operate a SMIE must be issued by the IRD, in a system established by the Directorate of Radioprotection and Nuclear Safety (DRS/CNEN). The IRD sector responsible for the process and systematic certification and/or accreditation of SMIE in Brazil is the Testing and Calibration Services Assessment Committee (CASEC). Obtaining this certification consists of analyzing the documentation delivered and after approval, the technicians responsible must pass a qualification exam. The SMIE is subject to the External Individual Monitoring Service Performance Assessment Test, by the IRD National Ionizing Radiation Metrology Laboratory. In conclusion, all SIMIE for whole body photons (chest dosimeter) must be authorized by CASEC/IRD/CNEN, which are responsible for calibrating, reading and interpreting the results obtained through individual monitoring devices and measurements of radioactivity in the body human or in biological samples for dose assessment. The data sent to the IRD by the SMIE is stored in a database with a web interface called External Occupational Dose Management, where it is stored for up to five years.
