Elemental Analysis of Two Rupee Indian Coins by EDXRF Technique
نویسنده
چکیده
Energy Dispersive X-Ray Fluorescence (EDXRF) technique has been used to study two Rupee Indian coins minted during the period 1993 to 2010 for their elemental concentrations. From the analysis of the coins, it is found that the coins are made of binary alloy and it was observed that from 2005 onwards, the composition of the coins has been changed from Cupro-Nickel to Ferritic Stainless Steel (FSS).
