From December 17-21, 2018, the U.S. Nuclear Regulatory Commission Radiation Sources Regulatory Partnership (RSRP) visited the Republic of the Congo. Mr. Grigol Basilia, on behalf of the RSRP, met with officials from Congo-Brazzaville’s radiation safety regulatory authority, the General Department of Mines (GDM) and installed the Advance Regulatory Information System (ARIS) Version 2.5 software. In addition, Mr. Basilia provided training on the use of ARIS, particularly the Radiation Sources Database (RASOD) module, and trained the ARSN staff on the process for conducting a national inventory of radiation sources and creating a national registry using the RASOD module. Twenty-four members of the GDM technical and other government ministry staff participated in the training. In addition, two senior members of the National Agency for Radioprotection (ANR) of the Central African Republic visited Brazzaville and participated in the software installation and in the training. GDM and ANR will begin their respective inventory processes in 2019.
