Radiological Hazard Resulting from Natural Radioactivity of Soil in East of Shazand Power Plant
Introduction: Nuclear radiation is potentially harmful to humans and soil contamination with radionuclides is the main source of human radiation exposure. These radionuclides can., enter to human body through the food chain. In this study, 34 soil samples were collected from between Arak city and Shazand Power Plant over 20 km length and analyzed. Materials and Methods: The specific activities ...
متن کاملGamma radiation measurements and dose rates in commercially-used natural tiling rocks (granites).
The gamma radiation in samples of a variety of natural tiling rocks (granites) imported in Cyprus for use in the building industry was measured, employing high-resolution gamma-ray spectroscopy. The rock samples were pulverised, sealed in 1-l plastic Marinelli beakers, and measured in the laboratory with an accumulating time between 10 and 14 h each. From the measured gamma-ray spectra, activit...
متن کاملAssessment of natural radioactivity levels for Karadağ Mountain, Turkey
Background:The natural radioactivity levels in soil samples of Karadağ Mountain in central Anatolia region have been determined. Materials and Methods: Analyses on the collected samples were performed to determine gross alpha and beta radioactivity concentrations by using a gas-flow proportional counter and the concentrations of 238U, 232Th and 40K by using a NaI(Tl) scintillation detector. Res...
متن کاملNatural Radioactivity and Dose Assessment for Brands of Chemical and Organic Fertilizers Used in Saudi Arabia
The activity concentration of naturally occurring radionuclides K, Ra and Th have been measured in different brands of fertilizer samples in Saudi Arabia using sodium iodide gamma spectrometry. The results of measurements showed that the mean (ranges) of specific activities for Ra, Th and K activities in the nitrogen, phosphorus and potassium fertilizers are 64 (35.8 120.7), 17 (3.2 56.8) and 2...
متن کاملNatural Radioactivity Concentrations and Dose Assessment in Shore Sediments along the Coast of Greater Accra, Ghana
Radioactivity concentration of Naturally Occurring Radioactive Materials (NORMs) in shore sediments (samples) collected along the coast of Accra were analyzed using a gamma spectrometry with a high purity germanium detector. The specific activity concentrations range from 8.60 Bqkg to 61.01 Bqkg with a mean of 29.78 Bqkg for K, 0.62 Bqkg to 148.80 Bqkg with a mean of 22.04 Bqkg for Ra and 0.17 ...
