TETRA radio exposure up to 6.0 W/kg showed no immediate cognitive harm in healthy men during 2.5-hour testing sessions.
Plain English Summary
German researchers exposed 30 healthy young men to TETRA radio signals (used by police and emergency services) at two different power levels for 2.5 hours each. They found no negative effects on cognitive performance, mood, or physical complaints, with some tasks actually showing slight improvement during exposure.
Why This Matters
This study provides important data on TETRA radio systems, which operate at 385 MHz and are widely used by first responders across Europe. The exposure levels tested (1.5 and 6.0 W/kg) are substantial - the higher level exceeds typical cell phone exposure by a factor of three to six. What's particularly noteworthy is that this research comes from Charité, one of Europe's most prestigious medical institutions, and used rigorous double-blind methodology with 30 participants across nine testing sessions each.
The finding of no adverse effects, and even some performance improvements, challenges assumptions about acute EMF impacts on cognition. However, the study's 2.5-hour exposure window tells us nothing about long-term health effects from occupational TETRA use. Emergency responders and security personnel often carry these devices for entire shifts, sometimes for decades. The reality is that short-term cognitive testing, while valuable, cannot address the cancer risks or other chronic health effects that concern many EMF researchers.

Specific exposure levels were not quantified in this study.
