Abstract: The processes of light attenuation in biological media are considered in details. The techniques of defining attenuation coefficient, plotting scattering indicatrix, calculating erythrocytes, measuring blood temperature under the action of laser radiation are described. The coefficient values depending on the radiation wave length and concentration of scattering centre have been obtained in the experiments. The angular radiation dispersion is plotted, the temperature dynamics is found out. Influence of erythrocytes on laser light attenuation when passing through blood is described. The graphs of attenuation coefficient dependence on the quantity of red cells per 1 mkl of blood for the wavelength of 632 and 890 nm are plotted. Plotting indicatrix and temperature measurement is performed for the wavelength of 632 nm.
