In order to set in place such a system in a country, there is an essential necessity to design a special organizational structure in the areas of disaster management. The main objective of this study...

Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. Radionuclides can affect human health by transferring from soil to plants and entering the human body. In this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...

To this date, research on crisis informatics has focused on the detection of trust in Twitter data through the use of message structure, sentiment, propagation and author. Little research has examined the usefulness of these messages in the crisis response domain. Toward detecting useful messages in case of crisis, in this paper, we characterize tweets, which are perceived useful or trustworthy...

Due to their often unexpected nature, natural and man-made disasters are difficult to monitor and detect for journalists and disaster management response teams. Journalists are increasingly relying on signals from social media to detect such stories in their early stage of development. Twitter, which features a vast network of local news outlets, is a major source of early signal for disaster d...

In the literature on the recovery of societies from natural disasters, a dominant theme is the importance of pursuing and achieving sustainable recovery. Sustainability implies that recovery efforts should aim to (re-) build, maintain, and, if possible, enhance the quality of life of members of the disaster-stricken community in the short and long term. In this paper, we propose a capabilities-...

Since 1980, over 2 million people have died as an immediate result of natural and man-made disasters and by 1992, the refugee population registered nearly 16 million people. This article reviews the human impact of disasters as a composite of two elements: the catastrophic event itself and the vulnerability of people. It also examines the specific case of women and children in the current world...
