The experimental layout designed to study properties of focused parametric X-ray radiation generated by relativistic protons in a bent crystal and parametric X-ray radiation generated by relativistic ions and positrons at accelerator U70 is described. Preliminary results of measurements of spectra of characteristic and parametric X-rays observed at 50 GeV proton beam are shown and discussed. The origin of the background radiation that obstacles for detail research of the PXR properties at proton beam is identified. Moreover, the distribution of the ionization losses of relativistic charged particles in the X-ray detector similar to Landau distribution is measured and discussed.
