标题：In-situ assessment of natural terrestrial-radioactivity from Uranium-238 ( 238U), Thorium-232 ( 232Th) and Potassium-40 ( 40K) in coastal urban-environment and its possible health implications
摘要：The risk of natural terrestrial radioactivity on human health is often underestimated, and environmental safety awareness is necessary. Hence, this study aims to assess natural sources of gamma radiation emitter in coastal urban-environment using the radiometric technique. The dosage of gamma radiation from a parent radionuclide such as Uranium-238 (
238U), Thorium-232 (
232Th) and Potassium-40 (
40K) and were measured using portable gamma spectroscopy. The result showed that the measured value of
238U activity was between 10.81
