The radioactive background of the eastern side Lesvos Island in Greece, an island rich natural radioactivity, was studied by means gamma ray spectroscopy. Dose rates and concentrations radionuclides (232Th series, 226Ra 40K) 137Cs were measured in-situ laboratory, respectively. A total twenty soil samples ten beach sand collected processed according to IAEA protocol. For measurement dose rate d...

Introduction: Considering the risk of radiation, the measurement of the natural radiation sources seems to be necessary. In this study, the concentrations of the natural radionuclides, namely 226Ra, 232Th, and 40K, were measured in the soil samples taken from different locations of Golestan, Iran. The measurement results can also be used as a baseline to evaluate the impact of non-nuclear activ...

Manzala Lake, the largest in Egypt’s Nile Delta, has significant human activity. The Lake’s ecological condition recently been impacted by a increase agricultural, industrial, and urban wastewater discharge. Avaluable tool for monitoring water quality of Manzal aLake is sensitivity invertebrate species to various types pollution, such as radioactive contamination. Activity concentrations radion...

Background: The natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: The natural radioactivity levels (226Ra, 232Th and 40K) in the ceramic tiles were measured using high-purity germanium detector system (HPGe) and the related radiological hazards were assessed by radium equivalent activity (R...

Background: Natural Radioactivity, though natural requires concentration monitoring, especially for the health/ environmental checks of the populace. Materials and Methods: The activity concentrations of 40K, 238U and 232Th in the waters from wells with depths ranging between 141.0 - 214.0 feet were randomly sampled and determined from 20 locations in Ago-Iwoye town in South Western, ...

Background: Health hazards associated with exposure due to the natural radioactivity which is a part of our physical environment are of great concern. In order to assess the risks associated with exposure due to the natural radioactivity in soil and building materials, extensive studies have been carried out all over the world. The most commonly encountered radionuclide’s are 238U, 2...

This article presents the results of studies content natural (228Ra, 226Ra, 232Th, 40K, 210Po, 210Pb, 238U) and technogenic (137Cs, 90Sr) radionuclides in drinking water from centralized (wells) decentralized supply sources observation area Belarusian NPP, performed 2016 to 2020 within framework radiation hygienic monitoring at stage construction NPP.

Mining generates significant amounts of waste that can represent a source contamination for areas close to the extraction area, generating negative impact both on environment and health people. This study aims evaluate radiological risk derived from exposure natural radionuclides contained in tailings Peruvian gold mines establish whether be used as raw materials building materials. The mine co...
