Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...

The objective of the present paper is the demonstration of the potential and advantages of Bayesian networks for the application in risk assessments for natural hazards. For this purpose, a general framework for natural hazards risk assessment is presented and a brief introduction to Bayesian networks is provided. The methodology is then applied to rating systems for assessing rock-fall hazard ...

Impact from natural hazards is a shared global problem that causes tremendous loss of life and property, economic cost, and damage to the environment. Increasingly, many natural processes show evidence of nonstationary behavior including wind speeds, landslides, wildfires, precipitation, streamflow, sea levels, and earthquakes. Traditional probabilistic analysis of natural hazards based on peak...

In 2008, the world was hit by some of the worst natural disasters. The Cyclone Nargis killed over 140,000 people and led to 10 billion financial losses. The Great Sichuan Earthquake caused over 60,000 deaths and 20 billion of estimated property damages. How do we get prepared for natural hazards? How do we enhance our resilience to natural hazards? Part of the answer lies in innovative techniqu...
