Abstract

The impact produced on rat blood corpuscles by attenuated geomagnetic field was investigated in model experiments with the use of specially designed shielding and imitation chambers. The shielding chamber, intended to provide 40-fold attenuation of the magnetic field, was made in the form of a cylinder covered with several layers of amorphous soft magnetic nanocrystalline material AMAG-172. We observed reliable granulocytopenia effect and tendency to erythropenia, indicators of bone marrow suppression, which were apparently caused by changes in the physical characteristics of the environment. We showed that via changes of their quantitative and qualitative characteristics blood corpuscles execute compensatory function aimed at reducing the effects of external magnetic field. Thus, we conclude that the response of the hemostasis system depends not only on species peculiarities but also on the magnitude of the attenuated geomagnetic field and duration of the animal’s exposure to it. Data were obtained demonstrating that there must be one week delay in the reaction of the organism on the external influence connected with placing the animal in shielding and imitation chambers.
