conclusions based on the results of this study, although radiographic findings are not diagnostic in ptb, they are helpful if the assessment associates with the view of clinical manifestations and sputum smears. patients and methods in this retrospective descriptive-analytical study, 376 patients who had been confirmed with ptb were referred to birjand health care center from 2001 to 2006. out ...

Chemical reconnaissance, defined as hazards detection, identification, and monitoring, requires tools solutions which provide reliable precise data. In this field, the advances of artificial intelligence can be applied. This article aims to propose a novel approach for developing chemical reconnaissance system that relies on machine learning, modelling algorithms, well contaminant dispersion mo...

Marine sediment samples were collected along the Jeddah coast, Red Sea, Saudi Arabia, in order to assess radiation hazards and exposure human marine living organisms. Using collaborative techniques, grain size, mineralogical characteristics, natural radioactivity investigated. To examine influence of characteristics over distribution measured radionuclides, resulting data statistically processe...

This study was carried out to determine the presence of main radionuclides from natural and artificial radioactivity in soil Kosovo, using gamma-ray spectroscopy. The mean activity concentration for Ra-226, Th-232, K-40, Cs-137 22.32 ± 1.41, 22.14 1.31, 358.16 8.85, 12.94 0.44 Bq/kg, respectively. Radium equivalent ranged 47 100 Bq/kg. calculated values gamma index (Iγ), external hazard (Hex), ...

Background: Thirteen (13) types of building tiles and Sharp sand commonly used for building purposes were collected for their radionuclide contents analysis. Both imported and locally produced building tiles were examined.  Materials and Methods: The samples of tiles and sand were crushed to powder and they were prepared such that their content could be examined by the use of gamma-ray spectrom...
