Current state of the art of unmanned systems with potential to be usedfor radiation measurements and sampling : ERNCIP thematic group Radiological and nuclear threats to critical infrastructure Task 3 deliverable 1

There is a significant potential in the use of unmanned remote controlled vehicles in sampling and measuring radiological events. No attempts to standardise sampling and measurement methods using these types of vehicles have yet been made. Common standards would simplify the use of remote controlled vehicles in an emergency scenario and would thus be very valuable in critical infrastructure protection (CIP). The main advantage of using unmanned systems in radiological events is the protection of the human personnel involved. This report is about current state-of-the-art of unmanned systems that have potential to be used for radiation measurements and sampling. It is believed that search and rescue robotics is the domain that is closest to the robots applicable to the radiation measurement scenarios. Therefore, a definition for search and rescue robots and outlines of their major subsystems are given. This is followed by a review of deployment scenarios for search and rescue robots outlining case studies of major emergencies at which robots have been deployed — with an assessment of their value to the emergency services. Additionally, research and development in search and rescue robotics, including current projects, testing environments and search and rescue robotics competitions, is outlined. Furthermore, this report shows unmanned robots and concepts for sensor systems capable of radiation detection based on state-of-the-art radiation sampling using unmanned ground vehicles, unmanned aerial vehicles with rotary wings or unmanned aerial vehicles with fixed wings

Critical parameters and performance tests for the evaluation of digital data acquisition hardware

Technical Report by the Joint Research Centre, JRC93260; EUR 26976 EN; 32 pags.; 16 figs.;Recent developments of digital data acquisition systems allow real-time pre-processing of detector signals at a high count rate. These so-called pulse processing digitizers are powerful and versatile instruments offering techniques which are important for nuclear security, critical infrastructure protection, nuclear physics and radiation metrology. Certain aspects of digital data acquisition affect the performance of the total system in a critical way and therefore require special attention. This report presents a short introduction to digital data acquisition, followed by a discussion of the critical parameters which affect the performance in the lab and in the field. For some of the parameters, tests are proposed to assess the performance of digital data acquisition systems. Good practices are offered to guide the selection and evaluation of digital data acquisition systems. More general performance criteria which are not specifically related to digital data acquisition systems are discussed separately.Peer Reviewe
