AbstractIn order to effectively respond to and minimize the psychological impact following disasters, such as radio-nuclear ones, it is essential to understand the mechanisms involved in such conditions and how to prevent and treat the psychological impacts, including those related to acute traumatic stress and its consequences across life span. Radio-nuclear emergencies may cause psychological traumatic stress, with its potentially significant consequences in mental health, with both short and long-term effects, which extend beyond the individuals directly affected. Ionizing radiation cannot be perceived by human senses and most people are unaware of the magnitude of its effects, which could result in feelings of helplessness and vulnerability. Those situations with a high degree of uncertainty, regarding potential future health effects, are more psychologically traumatic than others. The present century has witnessed a steady increase in the number of publications concerning the mental health impact of traumatic events, showing the need of increasing the study of traumatic stress and its impact on mental health. A prompt, planned and effective response to manage disaster-induced acute traumatic stress may prevent the evolutionary reactions of traumatic stress into disorders or even chronic stress diseases that can appear after a nuclear or radiological emergency.
