Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human health. Material and Methods: In this research 10 travertine samples were collected ...

The 12 NaI(Tl)-detector gamma-ray spectrometry system (GSS) “Romashka”[1,2] has recently been equipped with a new computer controlled HVSys 16 channel high-voltage power supply with preselected single channel polarity [3] (Fig.1). In order to do some preliminary checks of the GSS chains’ characteristics, a single channel gamma-spectrometry tract was commissioned. It was consist of a single Roma...

The surveys of natural gamma-emitting radionuclides in rocks and soils from the Ezine plutonic area were conducted during 2007. Direct dose measurement using a survey meter was carried out simultaneously. The present study, which is part of the survey, analysed the activity concentrations of U, Th and K in granitoid samples from all over the region by HPGe gamma spectrometry. The activity conce...

Introduction: Although there are several ways to relief pain in metastatic patients, the use of radionuclides is one of the known and effective ways to relieve the pain caused by bone metastases. The purpose of this study was to assessment of radiation dose distribution of different radioisotopes used to treatment and pain relief patients in a bone-based model based on Monte C...

Pure tungsten (W), irradiated to 3.5 dpa in a target of the Swiss neutron spallation source (SINQ), was characterized using high-sensitivity HPGe gamma ray spectroscopy identify present radionuclides. Synchrotron X-ray absorption used quantify amount Re produced W. An atomic concentration 0.61% W determined from height L3-edge edge jump. Analysis local structure extended fine (EXAFS) spectra in...

The distribution of radionuclides and heavy metals (carcinogenic non-carcinogenic) in soil plants grown lead contaminated areas were determined using gamma spectrometry AAS (Atomic Absorption Spectrometry). values Dout (outdoor dose rate) Din (indoor found to vary from 49.10 96.59 nGy h-1 with a mean value 73.75 97.30 191.67 143.39 for Kawo; 51.64 105.26 75.36 104.43 205. 87 157.13 Magiro. weig...

The reference values of the massic activities of each nuclide and their associated standard uncertainties were established based on the certified activity value of the standard solutions used for spiking the soil, taking into account the successive dilution steps, the mass of spiking solutions and the dry mass of the soil being spiked. Radionuclide Certified Value Bq kg Standard combined uncert...

The present study aimed to measure the activity concentration of natural radionuclides in the locally used building materials from Kilpenthaur, Tiruvannmalai Dist, Tamilnadu, India was investigated with an aim of evaluating the radiation hazard arising due to the use of these materials in the construction of dwellings. The concentrations of natural radionuclides Ra, Th and K in four types of bu...
