For modelling the virtual environment we used Unity software for the land creation, and Autodesk 3ds Max for the scenery and objects. We include in the Unity core radiation detectors and avatars. For the development of scenarios on the approach to individuals suspected of carrying radioactive materials, we analysed practices, procedures and the organization of radiological protection agents during events in the 2014 FIFA World Cup. Results indicated that the Collaborative Virtual Environment are suitable for training simulations in emergencies, because it was able to represent scenarios quite close to potential emergency situations. 1. Introduction To The recent scale and frequency of terrorist acts illustrate the increasing complexity faced by professionals and rescuers. With the proximity of the Olympic Games in 2016, Brazil is prone to terrorist attacks. The government and the organizations have created emergency managements to ensure normality of those events. The objective of this research is to create a Collaborative Virtual Environment CVE for training and assessment of collaboration in emergency prevention and response situations in major events. The management of emergency situations at an event is a complex problem that involves dynamic situations, which may not be easily anticipated. This emphasizes the potential complexity of the contexts in which organizations operate and, consequently, people involved in the execution of multiple tasks, from activities that require intense cognitive effort, often are challenged to adapt dynamically to maintain the productivity of the organization in satisfactory levels of performance, which often prevents them from reflecting on the result of their actions and learn from them. Emergency situations require decision-making occurring under substantial uncertainty, because the information comes from inferences or indirect sources. As a result, it is impossible to describe and completely how to control the system (Woods and Hollnagel, 2005). Under this environment, organizations such as the military, nuclear emergency first responders, firefighters, among others, have increasingly used simulation exercises to training their professionals (Voshell, 2009). This is reflected in the search for new technologies to simulate, explore and test new forms of operations aimed at solving difficult situations or to prevent future emergencies (Hintze, 2008). Therefore, it is important to create tools that address the methods and techniques to assist in the prior training of security agents, for example, the detection and approach people carrying radioactive elements. Simulation exercises serve as imaginary future situations to explore possible responses to events (Voshell, 2009). Therefore, exercises should be planned to address the cognitive skills that must be developed to respond an emergency situation. The purpose and scope of these exercises may include the training of responders, providing practice opportunities in mew situations, evaluation of new technological systems, building trust on trainees, identifying critical decisions, improving coordination, and testing the plans in the light of new threats.
