Research of radiomodification properties of nanoparticles are high relevant. Samples of cells cultures line Hela was irradiated to absorbed doses of 5, 7.5, 10 Gy on arrangement Xstrahl 300 with 200 keV energy of X-ray after three days CONPs have been added in medium. The results allow us to make preliminary conclusion that the early adding concentrations 50 μcg / ml of CONPs increase the sensitivity of cancer cells
