In rat brains exposed to 900 MHz radiofrequency radiation, only the increase in protein carbonyl was statistically significant (p < 0.001).

Plain English Summary

Summary written for general audiences

Researchers exposed male rats to 900 MHz radiofrequency radiation for 2 hours per day, 7 days a week, for 10 months, then measured beta amyloid protein, protein carbonyl, and malondialdehyde in the brain. Beta amyloid protein, protein carbonyl, and malondialdehyde levels were found to be higher in the brains of exposed rats. Only the increase in protein carbonyl was statistically significant (p < 0.001).

Why This Matters

The study was carried out on 17 Wistar Albino adult male rats, with 10 in the exposed group and 7 in the sham group. Sham group rats were placed into the same carousel and underwent the same procedure, except the generator was turned off. The rat heads were exposed to radiation from a generator simulating mobile phones. The researchers concluded that 900 MHz radiation can be an agent to alter some biomolecules such as protein, but noted that further studies are necessary.

Quick Questions About This Study

Researchers measured beta amyloid protein, protein carbonyl, and malondialdehyde levels in the rat brain.
Only the increase of protein carbonyl was statistically significant (p < 0.001), while beta amyloid protein and malondialdehyde levels were also higher but not significantly so.
Rats were exposed to 900 MHz radiofrequency radiation for 2 h per day (7 days a week) for 10 months.
The researchers suggested that 900 MHz radiation can be an agent to alter some biomolecules such as protein, and called for further studies.
