It was found that irradiation of a water solution of NaCl with the diffractometer DRON3-M (Russian device) had a large influence on two-step processes of crystallization. The irradiation in the first stage of crystallization of the solution produces metastable radicals of water and excited seeds, which stimulate a very fast crystallization after switching off irradiation. After the crystals reach a sufficient size, the crystal growth can be explained by creation of vacancy-interstitial pairs in the growing crystal due to irradiation. The increase of linear dimensions of the growing irradiated crystals is proportional to the square root √t of crystallization time because most important place in crystallization takes the ions diffusion by irradiated vacancies.
