title: Calibration of bone mineral and heavy metal measurements using doped wall-less gel phantoms of arbitrary form.
abstract: Cylindrical gel phantoms of 2% agarose concentration were used as wall-less phantoms of arbitrary shape for calibration purposes in non-destructive measurements of bone mineral and heavy metal concentration using XRF. The counts of the coherently and incoherently scattered photons with no sample present should be subtracted as "background" to get a linear relationship between the ratio of the coherently and incoherently scattered photons and the bone mineral concentration for phantoms of arbitrary diameters.
