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 ...

Estimating 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 ...

Terahertz 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...

The Types and Usage of Building materials in the West Iwan of Takht-e Soleymān

The western iwan of the Takht-e Soleymān is one of the most important buildings in this area. Based on some accounts, this iwan was constructed during the Sāssānid period and the Ilkhanate kings restored it after 700 years. This unique structure is statically unstable and needs strengthening. To this end, becoming familiar with the building materials and their use in this structure are importan...
