Validation of classical quantitative fundamental parameters method using multivariate calibration procedures for trace element analysis in ED-XRF
(Royal Soc Chemistry, 2014)
In this study, the X-ray intensities obtained from 76 soil samples were converted to concentrations by means of the Epsilon software program applying the fundamental parameters method (FP). Various National Institute of ...
Precision and accuracy of ST-EDXRF performance for As determination comparing with ICP-MS and evaluation of As deviation in the soil media
(Pergamon-Elsevier Science Ltd, 2014)
The present study was conducted to (i) determine the precision and accuracy of arsenic measurement in soil samples using ST-EDXRF by comparison with the results of ICP-MS analyses and (ii) identify the relationship of As ...

(Springer, 2015)
The aim of the study to determine the level of gross alpha and beta activity concentrations in tap waters in dwellings of Rize province from North part of Turkey after 27 years from Chernobyl disaster. the activity ...
Radioactivity and heavy metal concentrations in various honey samples
(Scibulcom Ltd, 2015)
In this study, the contents of natural radionuclide K-40 and fission product Cs-137 in floral honey samples from Rize and some other cities in Turkey, were investigated. the results indicated that 80% of honey samples were ...
Comparative studies of CdS, CdS:Al, CdS:Na and CdS:(Al-Na) thin films prepared by spray pyrolysis
(Academic Press Ltd- Elsevier Science Ltd, 2015)
In the present study, the spray pyrolysis technique was used to prepare pure CdS, 4 at.% Al-doped CdS, 4 at.% Na-doped CdS and (4 at.% Al, 4 at.% Na)-co-doped CdS thin films. It was found from X-ray diffraction data that ...
Effect of adding on the critical current density and lateral levitation force of bulk
