Consumption of fish containing elevated levels radionuclides can lead to undesirable health effects for consumers. People in the Singida Municipality harvest from lakes and ponds granite rocks which are linked with hazardous radioisotopes that may be bio-concentrated by fishes they consume. Currently, no study has ascertained these environments. This was carried out analyse radioactivity 226Ra,...

There is considerable interest in the chemical composition of smokeless tobacco products (STPs), owing to health concerns associated with their use. Previous studies have documented levels of 210Po, 210Pb and uranium in STP samples. Here, the levels of 13 α-particle and 15 β-radiation emitting radionuclides have been measured in a broad and representative range of contemporary STPs commercially...

The present work is the first systematic and large scale study on radioactive materials and heavy metals in surface soil around the Bayanwula prospective uranium mining area in China. In this work, both natural and anthropogenic radionuclides and heavy metals in 48 surface soil samples were analyzed using High Purity Germanium (HPGe) γ spectrometry and inductively coupled plasma-mass spectromet...

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...

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...

The paper presents the results of research on rare earth elements (REY) and selected radionuclides in barren rocks deposited a heap at mine belonging to Polish Mining Group (the largest producer hard coal EU countries). maximum concentration REEs determined silstones was 261.6 mg/kg sandstones 221.2 mg/kg. average uranium thorium content 6.8 11.6 mg/kg, respectively. On other hand, samples burn...

The concentrations of primordial radionuclides (226Ra, 232Th and 40K) in commonly used building materials (brick, cement and sand), the raw materials of cement and the by-products of coal-fired power plants (fly ash) collected from various manufacturers and suppliers in Bangladesh were determined via gamma-ray spectrometry using an HPGe detector. The results showed that the mean concentrations ...

Radioactivity measurements for naturally occurred radionuclides of 40K, 226Ra, 228Ra were carried out in some agricultural products harvested from two oil fields within the Nigeria Delta Region of Nigeria. The values obtained were used to determine the excess lifetime cancer risk (ELCR) and the radiation health hazard indices. Results show that the mean calculated ELCR values obtained from vege...
