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 کاملUltrasonic NDT of building materials based on wave features analysis
Abstract An ultrasonic technique has been experimented for non destructive testing of building structures. The Through Transmission Technique has been applied, processing the wave incident on a grid of detecting probes after it has been transmitted through a trachite stone masonry with an inside cavity. Several parameters associated with acoustic waves propagating through the structure have bee...
متن کاملEnergy Simulation and Management of the Main Building Component Materials Using Comparative Analysis in a Mild Climate Zone
The objective of this study is to evaluate the energy efficiency of residential buildings by using natural energy and optimizing the choice of materials for heat and cold saving with the Ecotect simulation software. According to analysis and simulation was found that the optimum material of main building components in a mild climate zone of Rasht city is the Brick Conc block Plaster for wall wi...
متن کاملTerahertz characterisation of building materials
To obtain realistic models for propagation channels in future picocellular indoor terahertz communication systems it is necessary to know the reflective properties of building materials found in a typical office environment. The angular dependent reflection coefficients of different building materials were determined using terahertz timedomain spectroscopy in transmission geometry and Fresnel’s...
