An attempt was made to find an explanation of the inverse oxygen effect (protective effects of oxygen in irradiated media). Experiments carried out with irradiated pepsin dissolved in phosphate or acetate buffer showed that the inverse oxygen effect increases with decreasing albumin concentration. With 0.1% albumin and over the inverse oxygen effect is negligible. In pure slightly acidified (pH-4.5) water without buffer neither the oxygen effect nor the inverse oxygen effects were observed even with very low albumin concentrations. Thus it appears that the presence of a third protector component (buffer) is imperative before the inverse oxygen effect takes place. With a buffer, but in the absence of oxygen, the radiation effect is identical to that in pure water. (R.V.J.)
