In the last decade, substantial progress has been made in improving safety & security for nuclear material worldwide, both by states' own domestic actions and through international cooperation. Al Qaeda has continuously expressed interest in unleashing radiological terrorism by building and using radiological dispersal devices (RDDs), known as “dirty bombs” for instance. Common radioactive materials, such as commercial radioactive sources used in medicine, industry scientific research could fuel RDDs. Since 1998, in Albania a special centralized building exists for radioactive waste management and as a temporary storage facility situated inside the INP territory. Radioactive waste conditioned with or without shielding was successively placed into this building for long-term storage. So far, there have been several incidents worldwide with terrorism potential that involved nuclear waste materials and radioactive materials and its repository facilities, which may serve as a target by attacks of terrorism. DU was also feared to causes environmental contamination through it being spread, especially in territories and borders of our countries involving the risk and injuring of the civilian population.
