A significant increase of the hemoglobin loss by irradiated erythrocytes as well as a strong dependence of the rate of the increase of hemoglobin loss on the initial level of spontaneous hemolysis were revealed. It was found that at low power densities, the hemolysis degree increases quasi-linearily with the exposure time, while at higher power density (5 mW/cm²), this tendency is reversed after first 10 h of irradiation. Long-term irradiation seems to exert a protective effect against spontaneous hemolysis caused by blood ageing. The osmotic fragility test performed on samples exposed to 5 mW/cm² at different irradiation times showed that the osmotic resistance increased in time, reaching a maximum at the end of irradiation (60 h), while the osmotic resistance of the controls was constant.
