Cell phone-level radiation showed no immediate effects on melatonin production in rats after 14 days of exposure.

Plain English Summary

Summary written for general audiences

Researchers exposed 72 rats to cell phone-type radiation at 900 MHz and 1800 MHz for 2 hours daily over 14 days, then measured melatonin breakdown products in their urine to see if the radiation disrupted their natural sleep hormone production. They found no significant changes in melatonin levels compared to unexposed control rats. This suggests that short-term exposure to these specific radiation levels may not immediately disrupt the body's internal clock or sleep patterns.

Study Details

In this study, the effect of exposure to 900 and 1800 MHz GSM-like radiofrequency radiation upon the urinary 6-sulfatoxymelatonin (6SM) excretion of adult male Wistar rats was studied.

Seventy-two rats were used in six independent experiments, three of which were done with 900 MHz and...

The combined results of three experiments done with the same frequency were statistically analyzed. ...
