Calculation of fluorescence flux from individual microcrystals of minerals of simple form

摘要

The derivation of formulas for the calculation of fluorescence fluxes of chemical elements in microcrystals of minerals of simple form (parallelepiped) is given. Such calculations are necessary for the development of a technique for quantitative XRF determination of the content of trace elements in accessory minerals using the internal standard method. The example of fluorescence flux calculation for Ce and Th in monazite is given.
