Control of Unauthorized Transportation of Nuclear and Radioactive Materials across State Territories and Borders – Detection, Response and Decision Support

摘要

A new solution to control the illicit transportation of nuclear and radioactive materials is proposedand described. This solution consists in the creation of a system of gamma and gamma-neutron radiationmonitors and fundamentally new software/hardware package RAVEN (Radiation Alarm and Video EventNotification) which integrates different type monitors in a single network. The main purpose of this system is toanalyze and store data coming from radiation monitors, to process these data and to help the user to interpretthem. This ensures the user’s correct response to all the alarms triggered by radiation monitors and indicating thepresence of radioactive and/or nuclear materials in scanned objects. The developed system can integrate fixedradiation monitors that can be installed in different sites within not only one country but in different sitesworldwide in a single network. The system can be adapted to the local conditions and allows the user: (i) todetect minimum quantities of special nuclear and radioactive materials (specified by the national andinternational requirements) by their gamma and/or neutron radiation; (ii) to acquire, store and analyze digitaldata and video images related to cargos with radioactive materials crossing a state border or an object limits; (iii)to make these data accessible to users at different levels ensuring effective operation of both central alarmstations (state, regional or agency center) and local alarm stations (border cross points or object limits).
