Features of radial growth dynamics of english oak in the conditions of radioactive contamination of forests of Central forest steppe

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.
