It is shown that the overall thrusts of processes of xylogeneses of oak in conditions of radioac-tive contamination are consistent with pre-viously established researchers for oak forests of Central forest steppe. Irradiation, mostly with short-lived isotopes of iodine, caused changes in the activity of the lateral meristem of woody plants - cambium. The impact had relatively short time interval and affected mainly xylogeneses of early wood regardless of the age of forming layer of wood.
