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 ...

Development which is less attention to the environment, inefficient use of energy as well as the increasingly dense city make space for the concept of green building to grow even more in Indonesia . The purpose of this study was to determine the extent to which the implementation of green building principles in commercial buildings. There are three buildings complexes that were examined in this...
متن کاملAssessment 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 کاملnatural radioactivity of granites used as building materials in iran
the radionuclides 226ra, 232th and 40k concentrations measured as well as radiological parameters, for 14 granite samples that use in iran as building material were calculated. the measurements of the radioactivity concentrations were carried out at nuclear physics laboratory university of tabriz. this subject is important in environmental radiological protection, since granites are extensively...
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...
