View Original AbstractTwo weeks of 21-kHz magnetic field exposure showed no immune system effects in young rats, suggesting short-term intermediate-frequency exposures may not immediately compromise immune function.
Plain English Summary
Researchers exposed young rats to 21-kHz magnetic fields (similar to frequencies used in induction heating and some wireless charging) for one hour daily over two weeks to test effects on blood and immune system function. The study found no significant changes in immune cell activity, blood cell counts, or other immune markers, with only a minor phosphorus level change that remained within normal ranges. This suggests that short-term exposure to these intermediate-frequency magnetic fields may not substantially impact immune function in developing animals.
Study Details
The aim of this study is to investigate Effects of 21-kHz intermediate frequency magnetic fields on blood properties and immune systems of juvenile rats.
Male Sprague-Dawley rats (4-5 weeks old) were divided into three groups: Cage-control, sham, and 3.8...
Hematological parameters were not affected by IF-MF exposure. Other immune functions such as the cyt...
Our results suggest that exposure to 21-kHz sinusoidal IF-MF at 3.8 mT for 1 h/day for 14 days did not affect immune function in juvenile rats.
