Plain English Summary
Researchers exposed pregnant rats to radiofrequency radiation (10 MHz) that raised their body temperature to 42°C, combined with varying doses of a common industrial solvent called 2-methoxyethanol. They found that RF radiation changed how the chemical affected developing fetuses, making birth defects occur at different dose levels than expected. This suggests that RF exposure can interact with chemical toxins in ways that current safety guidelines don't account for.
Why This Matters
This 1997 NIOSH study reveals a critical gap in how we assess EMF safety. The research demonstrates that radiofrequency radiation doesn't just act alone - it can amplify or modify the effects of other toxic exposures. The 10 MHz frequency used here is within the range of industrial RF equipment, though the heating levels (42°C core temperature) are much higher than typical consumer device exposures. What makes this particularly concerning is that workers in electronics manufacturing, plastic sealing, and medical device industries face exactly these combined exposures daily. The study's conclusion that 'combined exposure effects should be considered when developing exposure guidelines' highlights a fundamental flaw in current safety standards, which evaluate EMF and chemical exposures in isolation. You don't have to work in these industries to be affected - we're all exposed to multiple environmental stressors simultaneously, yet safety testing rarely accounts for these real-world interactions.

Specific exposure levels were not quantified in this study.
Study Details
The purpose of the present research is to determine the effects of r.f. radiation (sufficient to maintain colonic temperatures at 42.0 degrees C for 10 min) on a range of doses of 2ME (0, 20, 40, 60, 80, 100, 120 and 140 mg kg-1) administered on gestation day 13 of rats.
Focusing on characterizing the dose-response pattern of interactions, this research seeks to determi...

These data indicate that combined exposure effects should be considered when developing exposure guidelines and intervention strategies.
