[en] Under the Comprehensive Nuclear Test Ban Treaty (CTBT), an International Monitoring System (IMS) is being developed worldwide which involve the development of monitoring stations encompassing seismic, hydroacoustic, infrasound, and radionuclide technologies. The main function of the IMS is for monitoring global nuclear weapon test. As a Member State to the Treaty since 23 July 1998, Malaysia has received various benefits including access to IMS data. Apart from being used for nuclear weapons test monitoring, IMS data also can be utilized for civil and scientific purposes. After more than two decades of CTBT membership, no dedicated study was conducted to assess the level of utilization of IMS data in Malaysia. Therefore, this study was conducted with the objective to assess the level of awareness about CTBT and the level of IMS data utilization among research institutions, universities and relevant government agencies in Malaysia. Online survey and desktop study involving research institutions, local universities as well as relevant government agencies were used in this study. Based on the analysis of the data obtained, this study concluded that the level of awareness and understanding of CTBT as well as the use of IMS data among research institutions, universities and government agencies is low. The study also found that there is a high level of interest among research institutions, universities and government agencies to know more about IMS data as well as its potential utilization for civil and scientific use.
