Summary:
This thesis deals with the radiological and nuclear emergency situations which are unusual circumstances or incidents that involve either an ionizing radiation source - requiring urgent action in order to reduce the serious effects on human health and safety, quality of life, property or the environment - or a risk that could have such serious effects .
A radiological or nuclear emergency may be the result of either a technological accident or incident (e.g. failure at a nuclear power plant), an incident at a radiotherapy facility that could typically include loss of source or overexposure to a patient, or personnel, a similar incident at an industrial radiography or industrial radiation facility, theft of a source or finding of an "orphan" source, an accident while transporting radioactive material, etc., or a terrorist act. In any case, the management of such situations is based on the triptych: prevention - treatment - rehabilitation.
The thesis focuses on terrorist attacks and focuses on prevention. It concludes with a table-top exercise proposal, as it is a common place that the planning and systematic conduct of exercises to deal with radiological or nuclear emergencies and the immediate / short-term management of the consequences of their occurrence, constitutes the most effective method for the regular and in-depth testing, training and evaluation of the operational readiness, adequacy and efficient coordination of the involved parties. A set of methodologies was used for the development of the exercise, as well as a tool / code for studying the spread of the radiological / nuclear factor.
The thesis is structured in 6 chapters which are briefly presented here after.
In Chapter 1 of the paper presents the radiological and nuclear factor involved in the respective emergencies. At the same time, the sizes and units used for its identification and characterization are defined.
Chapter 2 covers the international and national legislative and regulatory framework governing nuclear and radiological emergencies, while the chapter 3 provides definitions and information about nuclear terrorism.
In Chapter 4 the HotSpot code is presented. More specifically, its possibilities and limitations are presented, as well as the way in which it can be used to prevent and / or deal with an emergency.
In Chapter 5 the methodology of planning, development, implementation and evaluation of a radiological or nuclear emergency exercise is described. A relevant scenario is proposed regarding a terrorist attack on a critical facility in the country. The HotSpot code, which was presented in the previous chapter, is also used to develop the scenario of the exercise.
Finally, in chapter 6 the main points and suggestions for future research are mentioned.
