Measurement of Radii of the Irradiated Red Blood Cells using He-Ne laser


In this research, we have studied the effect of radiation on blood cells that were irradiated by Gamma rays, Beta particles and Alpha particles by means of determination their radii before and after radiation caused by the diffraction of Laser from the blood cells. A comparison has been made with the biological technique for measuring the radii of red blood cells. We found that there is good agreement between the biological and interference techniques, for the non-radiated cells. But, for the radiated cells. We found a clear different between these radii, i.e., measurement of the radii before and after the radiation about (100-1500 Ao) were increased to [O,AB,A] types, but it was decreased to [B] type.
