Plain English Summary
Japanese researchers used computer models to calculate how much radiofrequency energy (SAR) reaches a fetus when a pregnant woman wears a business radio transmitter on her abdomen at 150 MHz. They found that fetal SAR levels depend heavily on the distance from the antenna and the baby's position, though levels stayed below occupational safety guidelines.
Why This Matters
This study highlights a critical gap in our EMF safety standards: pregnant women face unique exposures that aren't adequately addressed by current guidelines. While the researchers found fetal SAR levels below occupational limits, this comparison is misleading. Occupational guidelines assume healthy adult workers, not developing fetuses whose cells divide rapidly and whose nervous systems are still forming. The finding that fetal position and antenna distance dramatically affect exposure levels underscores how unpredictable these exposures can be in real-world scenarios. What this means for you: if you're pregnant and work in an environment with radio transmitters or similar devices, maintaining distance becomes even more important than usual.
