From April 30 to May 2, 2024, OAP hosts a workshop preparing for the International Nuclear Security Advisory Service (INSServ) Mission on Measures for Nuclear and Other Radioactive Material Out of Regulatory Control and Response Systems at its headquarter. INSServ Mission is a service provided by IAEA to help member states strengthen their measures against material out of regulatory control. About 35 representatives from relevant authorities also actively participate in the workshop as they are gathering key information and related documents or evidence for the Mission which is taking place later this year.
