[The effect of roentgen rays on the transmembrane potential and on the electrophoretic mobility of polymorphonuclear granulocytes and FL-cells (author's transl)].

Two hours after X-irradiation at 37 degrees C in vitro at doses ranging from 50 rad to 20 krad the transmembrane potential and the surface charge of polymorphonuclear granulocytes and FL-cells showed a dose-dependent decrease. However, between two and four days after irradiation at 10 krad FL-cells revealed an increase in both transmembrane potential and surface charge. Small doses of ionizing radiation (e.g. 10 rad) resulted in aperiodically damped oszillations of membrane polarisation in leucocytes.
