[Effect of ionizing radiation on the chromatin fraction components in rat blood lymphocytes]. / Vplyv ionizuiuchoï radiatsiï na komponenty fraktsiï khromatynu limfotsytiv krovi shchuriv.

Changes in the level of blood lymphocyte chromatin degradation and relaxation were investigated after the whole body irradiation with doses up to 0.21 C/kg. It was shown that ionizing irradiation initiated the increase of nuclear endogenous Ca/mg-dependent endonuclease, and protease activities.
