The specific activity and spatial distribution of 238U, 232Th 40K were determined in the surface soil from Lișava uranium mining sector. This sector belongs to Banat district, an historically important area Romania (an with closed mines a radioactive waste dump). Gamma-ray spectrometry using high-purity germanium (HPGe) detector was used measure naturally occurring radionuclides soil. average a...

Background: A study on the migration characteristics of 238U, 210Po, 232Th and 40K within the soil to the wild plants in the Western Ghats were carried out. Materials and Methods: Concentrations of these radionuclides were measured in different depths of soil and from different species by employing gamma ray spectrometer and alpha counter. Results: The activity concentration of these r...

programs. 1 General coincidence summing problems and specific coincidence summing problems encountered when measuring these two radionuclides on filter papers were discussed in the last issue? In order to perform accurate measurements of 134CS and 60Co in liquid samples using Marinelli beakers, coincidence summing effects should be investigated. Liquid samples of 134Cs and 60Co were prepared in...

O.S. Ajayi, S.B. Ibikunle,

Background: The activity concentrations of some radionuclides in soil samples collected from 20 locations in 8 major towns in Oyo State, Southwestern Nigeria have been determined by gamma-ray spectrometry technique. Materials and Methods: The activity concentrations were determined using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The outdoor absorbed dose rates in air at ...

The radiological quality of drinking water is directly associated with the health population. Indeed, it well known that presence radionuclides in constitutes a risk for humans because consumption such increases likelihood incurring cancer. For this reason, all studies aimed at developing new methodologies qualitative and quantitative analysis radioisotopic composition are absolutely desired by...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can be dissolved into water. Evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. Materials and Methods In this study,10 samples were collected from ground...
