Nuclear analytical techniques have provided unique information in many fields due to their multi-elemental sensitivity, low limits of detection, ability to provide spatially resolved and/or quantitative profiling of trace elements, and, very often, traceability of results.Although these analytical techniques are readily available and routinely applied in research, there is still a considerable gap when it comes to routine forensics applications.The purpose of this e-learning tool is to help to bridge the gap between the practitioners of nuclear analytical techniques and forensic science stakeholder communities. It is directed at forensics specialists who wish to learn more about nuclear analytical techniques, and at nuclear techniques practitioners who wish to learn more about the requirements of forensic sciences.This course is an output of the Coordinated Research Project F11021 “Enhancing Nuclear Analytical Techniques to Meet the Needs of Forensic Sciences,?and its scope was expanded and translated into Spanish within the framework of the Technical Cooperation project RLA1017 "Applying Nuclear Analytical Techniques to Forensics for Analysing Firearms Crime Evidence".For additional information please contact: N.Pessoa-Barradas@iaea.org or Aliz.Simon@iaea.org? ? ? ? ??? ? ? ? ??
