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...

Background: There have been growing concerns about environmental pollution and public health issues associated with metal(loid)s and radionuclides. As a baseline for monitorisation, radioactivity and specific metal(loid) levels have been measured to investigate the estimated environmental health risks in Igdir province at the Turkish side of the border, in the vicinity of the Metsamor Nuclear P...

background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident.  rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...

Introduction: Artificial and natural radionuclides exist in the environmental materials, such as water, soil, rocks, and plant as well as in animals and human body tissues. Therefore, human being and environment are at constant radiation exposure. Regarding this, the present study aimed to determine the specific activities of radionuclides and perform the risk assessment wheat and barley sample...

background: this study was focused on the probability of carcinogen risk of low-level ingestion and dermal exposure with polycyclic aromatic hydrocarbons (pahs) from drinking water in tehran, capital of iran. methods: concentrations of 16 pahs were measured in the tap, bottled and heated tap water in four different seasons. using a questionnaire-based survey, exposure with pahs from drinking wa...

Background: Ondo city in Ondo State Nigeria includes Ondo East and West could be described as a research city due to antecedent number of research institutes. Materials and Methods: Dose due to radioactivity content of soil samples from sixteen waste dump sites in Ondo, Southwestern Nigeria was determined using gamma-ray spectrometer in order to evaluate the radiation hazard health profile and ...

Introduction: This Study has was  carried out to measure and detect the natural occurred radionuclide content including 226Ra, 232Th and 40K in the  Nile River sediments at various locations in Upper Egypt, from Aswan to El-Minya. Additionally, we determine the absorbed dose rate, the annual effective dose equivalent, and excess lifetime cancer risk also has been calculated. Material and Metho...
