Abstract: Public concerns about potential health risks of intermediate-frequency (IF) electromagnetic fields are increasing, especially as the use of induction-heating cooktops has spread extensively in Japan and Europe. In order to investigate the properties of IF electromagnetic fields, we examined the effect of exposure to a 23-kHz IF magnetic field of 2 mT for 2, 3, or 4 h on neutrophil chemotaxis and phagocytosis using differentiated human HL-60 cells. Compared with sham exposure, exposure to the IF magnetic field had no effect on neutrophil chemotaxis or phagocytosis. Previous studies demonstrated that exposure to a 23-kHz IF magnetic field of 2 mT (about 74-times the maximum value recommended by the International Commission for Nonionizing Radiation Protection guidelines) may affect the first-line immune responses in humans. To our knowledge, this is the first study to evaluate the effects of IF magnetic fields on cellular immune responses. We found that exposure to an IF magnetic field of 2 mT has minimal if any effect on either the chemotaxis or phagocytic activity of neutrophil-like human HL-60 cells.
