Assessment of radiological hazards of travertine rocks as building materials
Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human health. Material and Methods: In this research 10 travertine samples were collected ...
متن کاملEstimating radiation dose from building materials
Background: Natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. So, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. Materials and ...

متن کاملClassifications and Properties of Materials for Chairside Computer-Aided Design/Computer-Aided Manufacturing Dentistry: A Review
Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...
متن کاملBuilding a Digital Library for Computer Science Research: Technical Issues
Technical reports are available electronically at hundreds of internet sites around the world. A major impediment to their utility in computer science research is the difficulty in locating reports that are relevant to a particular area. We describe the implementation of a digital library for computer science technical reports that indexes every word in each report, covers a majority of compute...
