Criminalistics can be defined as that profession and scientific discipline directed to the recognition, identification , individualization, and evaluation of physical evidence in laboratory or even in crime scene investigations with the objective to presentation in court. For this purpose it uses the knowledge of many other areas, such as archeology, human identification, sound comparison, etc. The nuclear area also presents several challenges involving the response face to criminal activities. The International Atomic Energy Agency (IAEA) has encouraged member states to create an adequate structure for investigating criminal offenses related to nuclear security through a new activity called Nuclear Forensic Science. In this work we propose the establishment of a training course that encompasses the knowledge of nuclear and criminal science, capable of training professionals for acting in the area of investigating illicit activities related to nuclear safety.
