Beach rock samples collected from South East Coast of Tamilnadu was analyzed by natural radioactive measurements to detect the presence of radioactive elements. PIXE technique was used to obtain elemental composition of beach rocks. The PIXE analysis was carried out using 1.7 MV tandem accelerators with the energy of 2 MeV protons at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, Tamilnadu, India. The geochemical behavior of the elements in the region is discussed. The occurrence of the radioactive and non-radioactive elements is discussed for their geological significance. The results were used to assess environmental toxicity of heavy metals and radiation hazard in the study area.

“…The quantitative multi-element analysis of titaniferous magnetites was investigated using PIXE and EDXRF in an investigation by Nayak et al 135 Iron mineral phase characterisation and the determination of Fe 21 : Fe 31 ratio was also carried out using Mo ¨ssbauer spectroscopy. The concentrations of nineteen minor and trace elements were quantified using EDXRF and 18 elements were determined by PIXE.…”

The review also covers a survey of applications, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. During the current review period, trends were noted in the increased use of principal component analysis in the assessment of environmental data and chemometrics in the interpretation of XRF data in general, meticulous experimentation to model the emission spectra of X-ray tubes to improve the accuracy of FP correction procedures, a slowdown in reports on the development of ultra-high resolution cryogenic ED detectors, the use of EXAFS and XANES in fluorescence, as opposed to the more traditional absorption mode, continued interest in SR sources and interesting artefact measurements performed using XRF and related instrumentation. Instrumentation General instrumentation and excitation sourcesSeveral developments in the design of commercially available X-ray spectrometers feature in the literature during this review

“…Other ion beam techniques such as PIGE is better than PIXE when measuring some elements especially the low Z elements as self-absorption effect is completely avoided [2,3]. PIXE has many applications in the study of archaeology, environmental, biological, medicinal and forensic materials [4][5][6][7][8][9]. However, despite the numerous advantages of PIXE technique, standardization or calibration with certified reference materials before each experiments poses a major challenge to most researchers [10].…”

Standardization of proton induced X-ray emission for analysis of trace elements in thick samples

et al. 2019

View full text Add to dashboard Cite

This paper presents the standardization of Proton Induced X-rays Emission (PIXE) technique for the trace element analysis of thick standard samples. Three standard reference materials (SRMs) viz-à-vis titanium, copper and iron base alloys were used for the study due to their availability. The protons beam was accelerated up to 2.57 MeV energy by 5UDH-II tandem Pelletron accelerator and samples were irradiated at different geometry and durations. Spectrum was acquired using a multi-channel spectrum analyzer while spectrum analysis was done using a GUPIXWIN model for determination of elemental concentrations of trace elements. The obtained experimental data was compared with theoretical data and results were found in close agreement.
