The analysis of some of the Indian silver coins during British rule were analysed by Energy Dispersive X-Ray Fluorescence Technique. Eight elements namely Cr , Fe , Ni , Cu , Zn , As , Ag and Pb were estimated in this study which also seems to indicate the fragmentation as well as the impoverishment of the power for the regimes that had produced the studied coins. While Cu and Ag were present as major elements, other elements were found to be present in minor concentration.

Archaeological Objects

Coins are important archaeological objects that can provide useful information regarding preparation methodology and provenance. Their classification plays a fundamental role in dating historical events, in constructing trade routes and in establishing the welfare of population. Several Indian copper coins of different periods have been studied using Energy Dispersive X-ray Fluorescence (EDXRF) spectroscopic technique. The method is rapid, efficient, multi elemental and non-destructive in nature. Concentrations of the major and trace elements like Ca , Ti , V , Cr , Mn , Fe , Co , Ni , Cu , Zn , As and Pb have been estimated in these copper coins. In the present investigation, an attempt has been made to characterize some Indian copper coins of different periods using EDXRF technique.

The Relationship

The aim of this study was to determine the Fe and Zn concentrations in some leafy vegetables (cabbage, spinach, celery and lettuce) and in their growing soil collected from sites with different industrial activity; in fruiting body of wild edible mushrooms (Armillariella mellea) and in their substrate (soil) collected at different distances by a metal smelter, by using energy dispersive X-ray fluorescence (EDXRF) technique. A quantitative evaluation of the relationship of Fe and Zn uptake by the vegetables and mushrooms from soil was made by calculating the coefficient accumulation Ka. The results reveal that lettuce is a accumulator of Fe and Armillariella mellea is a accumulator of Zn.

Elemental Detection

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry is a nondestructive, rapid, multielement, highly accurate, and environment friendly analysis compared with other elemental detection methods. Thus, EDXRF spectrometry is applicable for production quality control, ecological environment monitoring, geological surveying, food inspection, and heritage analysis, among others. A hardware platform for the EDXRF spectrometer is designed in this study based on the theoretical analysis of energy-dispersive X-ray. The platform includes a power supply subsystem, an optical subsystem, a control subsystem, and a personal computer. A fluorescence spectrum analytical method is then developed to obtain the category and content of elements in a sample. This method includes qualitative and quantitative analyses. Finally, a series of experiments is performed. Results show that the precision of the proposed measurement method is below 8%, whereas its repeatability is below 2%.

Experimental Values

In this study, K shell absorption jump ratios (JK) and jump factors (rK) of specimens in the atomic number range of 40 ≤ Z ≤ 50 were measured using the energy dispersive X-ray fluorescence (EDXRF) technique. Related specimens were excited using 59.54 keV γ-photons that were radiated from a 241Am point source. Typical K X-rays emitting from specimens were detected from silicon drifted lithium (Si(Li)) semiconductor detector. Derived JK and rK values of related specimens were compared with calculated theoretical and other experimental values. The agreement of measured values was reasonable with theoretical calculations.
