TLDR
In this paper, the Gamma-ray Spectrometry of High Purity Germanium (HPGe) detector was used to measure the concentrations of natural and artificial radionuclides in soil samples collected from different areas of Chittagong City Corporation.Abstract:
The concentrations of natural and artificial radionuclides in soil samples collected from the different areas of Chittagong City Corporation were measured by using Gamma-ray Spectrometry of High Purity Germanium (HPGe) detector.The concentration of 238U was found to be in the range 25.66 ± 5.48 Bq/Kg to 48.87 ± 6.00 Bq/Kg with an average value of 39.11 ± 5.77 Bq/Kg, the activity concentration of 232Th was found to be in the range of 27.12 ± 7.07Bq/Kg to 64.71 ± 7.95 Bq/Kg with an average value of 45.65 ± 7.48 Bq/Kg , and the activity concentration of 40K was found to be in the range of 293.81 ± 75.36 Bq/Kg to 637.49 ± 81.88 Bq/Kg with an average value of 430.56 ± 76.79 Bq/ Kg. The level of natural radioactivity in the region has been compared with the other areas of the world and the world average. In the soil samples, the overall activity concentration of Uranium and Potasium has been found to be higher than that of the world average, and the activity concentration of Thorium has been found to be nearly of the world average and the activity concentration. The artificial radionuclide 137Cs has not been detected in the samples.read more

Environmental Radioactivity From Natural Industrial And Military Sources
TL;DR: In this paper, the authors proposed a system for reading environmental radioactivity from natural industrial and military sources, but end up in malicious downloads, where instead of enjoying a good book with a cup of tea in the afternoon, instead they are facing with some malicious bugs inside their laptop.

Radionuclides Measurement and Assay of Soil and their Corresponding Absorbed Dose Rate in Air In Aramoko-Ekiti, Nigeria
TL;DR: In this article, four radionuclides (137Cs, 238U, 232Th and 40K) were analysed in soil samples collected from Aramoko-Ekiti, South West Nigeria by a sensitive gamma-ray spectroscopic system consisting of a 7.6 cm × 7. 6 cm Nal(TI) scintillation detector interfaced with Canberra series 10 plus multichannel analyser.
