In this study, we evaluated the activity concentration of natural radionuclides (226Ra, 232Th and 40K) for fifteen (15) different brands of tile samples used for building purposes in Nigeria. The tile samples were analyzed using High purity Germanium gamma detector. The mean activity concentrations of 226Ra, 232Th, and 40K were observed to be 61.1 ± 5.5 Bq/kg, 70.2 ± 6.08 Bq/kg and 514.7 ± 59.8...

Today, urban transportation has attracted urban planners’ and researchers' attention because of air and noise pollution problems associated with it. In Shahrkord city in Iran, no plans have been made for sustainable transportation, and the available poor transportation infrastructure is not responsive to the growing population of the city. This issue has inflicted the city with serious problems...

Introduction: This study covered the assessment of the natural radioactivity levels and heavy metalsconcentration in dust samples collected from selected schools in the holy Governorate of Karbala. The purpose of thisstudy was to assess the radiological health and safety impact of dust pollution on the children going to school. Material and Methods:</...

introduction: the survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. implant success also is affected by the maintenance of the crestal bone around implants. the aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...

The radiological effects of mined tailings in some locations in Jos Plateau State have been estimated. The samples were collected from 14 different sites. The radio nuclides concentrations in the tailing samples were measured using gamma spectroscopy method. The average values of Ra 226 , Th 232 and K 40 obtained were 762.4Bqkg, 17258.3Bqkg and 5901.4Bqkg respectively. These radioactivity conce...

background: natural radiation is constantly present in the environment and is emitted from a variety of natural and artificial sources. it affects human body and environment. materials and methods: the activity concentrations of 238u, 232th and 40k have been determined by gamma ray spectrometer with an hpge detector in sediments of cauvery river, tamilnadu, india. results: the absorbed dose rat...

background: human activities such as mining enhance the radioactivity levels above normal background which can lead to an incremental increase in the radiation risk to the population. materials and methods: 20 tailing enriched soil samples collected around maiganga coal mine, gombe, northeast nigeria were assessed for their 226ra, 232th and 40k contents using hpge gamma-ray detector. results: t...
