Short-term TETRA radio exposure showed no cognitive impairment in healthy men, but this doesn't address chronic, multi-frequency EMF exposure.

Plain English Summary

Summary written for general audiences

German researchers exposed 30 healthy young men to TETRA radio signals (used by emergency services) for 2.5 hours at two different power levels to test effects on thinking abilities and well-being. They found no negative impacts on cognitive performance, mood, or physical complaints, with some measures actually showing slight improvement during exposure. This suggests short-term exposure to TETRA signals at these levels doesn't impair mental function in healthy adults.

Study Details

To investigate possible acute effects of electromagnetic fields (EMF) of two different levels of TETRA hand-held transmitter signals on cognitive function and well-being in healthy young males.

In the present double-blind cross-over study possible effects of short-term (2.5 h) EMF exposure of ...

Attention remained unchanged in two out of three tasks. In the working memory significant changes we...

The results of the present study do not indicate a negative impact of a short-term EMF-effect of TETRA on cognitive function and well-being in healthy young men.
