Abstract The purpose of this study was the use gamma spectrometry to characterize archaeological site Molina de Aragón, located in province Guadalajara Spain. To do so, a set samples with different historical influences have been selected. were analyzed by HPGe detectors, and X-ray fluorescence, know their chemical composition. statistical activity concentration radionuclides from natural radio...

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...

Background: Measurement of the radiation dose distribution is important in assessing the health risk a population and serve as reference in documenting changes to environmental radioactivity in soil due to man-made activities. Materials and Methods: The activity concentration of 238U, 232Th and 40K in soil samples obtained from different locations in Ajaokuta Local Government area was measured ...

High purity germanium (HPGe) detectors used in radionuclide assay systems such as Radionuclide Aerosol Sampler/Analyzer (RASA) systems must operate unattended for long periods of time. Currently, the performance and reliability of commercially available large (~100%) HPGe detectors are acceptable for the majority of laboratory applications. However, for remote systems designed for nuclear deton...

High-spin states of (84)Sr are populated through the reaction (70)Zn ((18)O, 4n) (84)Sr at the beam energy of 75 MeV. The measurements of excitation functions, γ-γ coincidences, directional correlations of oriented states (DCO) ratios and γ-transition intensities are performed using eight anticompton HPGe detectors and one planar HPGe detector. Based on the experimental results, we establish a ...

The radiation survey of the ambient environment was conducted using two gamma detectors and the measurement results were used in the computation of the mean external radiation dose rate, mean weighted dose rate, annual effective dose and the collective effective dose, which are 69 nGy h, 0.447 mSv y, 237 μSv and 0.126 × 10 man Sv y, respectively. A hyper purity germanium (HPGe) detector was use...

Specific activites of natural (40K, 226Ra and 40Th) anthropogenic (137Cs) radionuclides in 30 glutinous rice samples bought from some local retailers department stores Songkhla Province have been measured analyzed. Experiment results were carried out by using a high-purity germanium (HPGe) detector gamma spectrometry analysis system at Radiation Laboratory Thailand Institute Nuclear Technology ...

The present study examines the radionuclides ( 40 K, 226 Ra and 210 Pb) concentrations in soil plants collected from El Jadida agricultural area. transfer factors of to different components (stems, roots, leaves, fruits) was also determined assessed. include various vegetable crops, including pumpkin, zucchini, beans, fennel, potato, sunflower, broccoli, onion, carrot, cabbage, tomato, mallow t...
