Abstract: A method of determining the mean size of given solid particles in a fluid comprises passing two x-ray beams of different energies into the fluid. The energies of the two X-ray beams being such that the resulting intensity of fluorescent radiations emitted from the particles due to one beam is substantially independent of the mean size of the particles while the intensity of fluorescent radiations emitted from the particles due to the other beam is substantially dependent upon the mean size of the particles. A comparison of the intensities of these two types of emitted fluorescent radiations gives an indication of the mean particle size.
