Time of investigation:
  • after exposure

Main outcome of study (acc. to author)

At low power densities (0.8 and 1.36 mW/cm²), there is a quasi-linear increase in the degree of haemolysis with increasing time of exposure; at higher densities (5 mW/cm²), this tendency seems to be reversed after the first 10 h of exposure.
The data of the osmotic resistance of exposed erythrocytes show a progressive increase in osmotic resistance with time of exposure (at 5 mW/cm²).
