RSRP provided training on the Advanced Regulatory Information System (ARIS1.5) to Bolivian Institute for Nuclear Technology (IBTEN) throughout May 8-9. The objective of this activity was to upgrade Access-based RASOD/AUTHORIZATION software for accounting the disposition of radiation sources to ARIS 1.5, an SQL based system with improved user interface and new features. The RSRP instructors installed ARIS 1.5 and explained the advantages of having the new modules for AUTHORIZATION and LICENSEE. Detailed guidance was provided on successful installation/de-installation of ARIS 1.5 and system backup. Under the new concept of the LICENSE module, hands on exercises demonstrated improved methods of information management for facilities using ionizing radiation sources. Training was conducted by Grigol Basilia of the Department for Nuclear and Radiation Safety of Ministry of Environment and Natural Resources Protection of Georgia and Mario Rodriguez of AdSTM. Software was developed and is maintained by Nuclear and Radiation Safety Center of Armenia (N&RSC). ARIS 1.5 will be implemented as IBTEN continues with the inventory project under the support of the RSRP program.
