Abstract: Due to widespread of human exposure to electromagnetic fields, there has been increasing public concern
about the potential health risks from low-frequency electromagnetic fields; ELF-EMF. The magnetic fields (MFs) affects
functions of the living organisms, such as DNA synthesis and ion transportation through the cell membranes. In the
present work, the effects of short-term exposure to magnetic fields (MFs) prior to incubation were investigated on the
biophysical blood properties of chicks hatched from layer-type breeder eggs. The eggs were exposed to a MF of 0.75mT
at 50 Hz for 20, 40 and 60min before incubation. This study was performed by measuring the dielectric relaxation of
hemoglobin (Hb) molecules and the membrane solubility of red blood cells (RBCs) using the non-ionic detergent
octylglucoside. Exposure of the eggs to a MF increased the conductivity of the Hb molecules. The pronounced increase
in the conductivity of the exposed eggs might be attributed to an increase in the surface charge of the Hb
macromolecules, resulted from the formation of highly active molecular species. This speculation can be supported
bythe increase in the relaxation time of the exposed groups. The solubilization process of the RBC membrane indicates
a loss in the mobility of RBCs in the blood of hatching chicks.
