Radiological accidents can result in significant radiation exposures of workers and of the public. These accidents usually occur as a consequence of human activities in military, industry, medicine, agriculture and research, involving the use of radiation and radioactive substances that cause radiation exposure in addition to the natural exposure. The effects of radiological disasters must be promptly investigated and the assessment of doses estimated, in order to provide adequate medical treatment to the persons affected, study their impact in society, as well learning lessons for the future and prevent further accidents. In this paper we introduce the use of software multi-agents systems immersed in a geographical representation of the world, as a viable and economic option to simulate radiological accidents and assess doses. Build an environment, where the researcher can simulate a non-natural radioactive dispersion, in a delimited area, can furnish parameters for analyzing, studying and managing these dynamic systems.
