✦ Synopsis

The metal content of Colorado potato beetles elytra in Turkey was determined using the energy dispersive X-ray fluorescence method. A radioisotope excited X-ray fluorescence analysis using the method of standard addition is applied for the elemental analysis of Colorado potato beetles elytra. An annular 50 mCi 241 Am radioactive source and an annular 50 mCi 55 Fe radioactive source were used for excitation of characteristic K X-rays. An Si(Li) detector which has a 147 eV full-width at half-maximum for 5:9 keV photons was used for intensity measurements. The procedure of sample preparation and the results of analysis were presented.
