Analysis of Trace Elements in Bone by Radioisotope Induced EDXRF

Abstract

In order to obtain a correlation of lead in bone and osteoporosis and other toxic related disease a study was carried out on bones. Femoral head bone samples obtained from osteoporosis patients were analyzed using Cd109 induced EDXRF consisting of a Si(Li) X-ray detector spectrometer coupled to a PC based Multichannel Analyzer. Besides other trace elements, calcium and strontium were predominantly seen in all samples. Lead was also detected.

“…Energy Dispersive X‐ray Fluorescence spectrometry (EDXRF) is an elemental analysis technique, used to identify the elements present in a sample (both qualitatively and quantitatively) by counting the number of photons of each energy emitted from the sample, when an individual atom of the sample is ionized by an external source, resulting in emission of x‐ray photons of a characteristic energy or wavelength. Cobalt‐ 57 (Co 57 ) radio‐active source is used as the source of incident, low energy gamma radiation . The 122 keV and 136 keV gamma rays from Co 57 source enter the target (sample).…”

“…Cobalt-57 (Co 57 ) radio-active source is used as the source of incident, low energy gamma radiation. [23] The 122 keV and 136 keV gamma rays from Co 57 source enter the target (sample). They have sufficient energy to eject the K-Shell electrons (in addition to L-Shell, M-Shell electrons and so on) from atoms of the sample (target).…”
