The low energy photon counting rate normalized to the source-detector geometry showed an enhancement in intensities, when the source was placed in the vicinity of the detector. Isotopic X-ray source of known output /93mNb,55Fe and49V/ was used. This enhancement is interpreted to be due, at least, to the occurrence of diffractional coherent scattering with the lead collimator.
