Natural radioactivity in ceramic tiles and associated radiological hazards

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...

Natural radioactivity and human mitochondrial DNA mutations.

Radioactivity is known to induce tumors, chromosome lesions, and minisatellite length mutations, but its effects on the DNA sequence have not previously been studied. A coastal peninsula in Kerala (India) contains the world's highest level of natural radioactivity in a densely populated area, offering an opportunity to characterize radiation-associated DNA mutations. We sampled 248 pedigrees (9...

Natural radioactivity and heavy metal distribution in reservoirs in Ghana

The present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in Ghana. Heavy metal concentrations in all samples were generally within the WHO safe limits with the average activity concentrations of 238U, 232Th, and 40K in water being respectively 0.42±0...

Natural radioactivity in Indian vegetation samples

Background: Vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238U (uranium), 232Th (thorium) and 40K (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. Materials and Methods: Natural radioactivity, radiological hazards and annual effective dose assessment was carri...
