High levels of cellphone radiation linked to cancer in male rats

The study exposed 3,000 rats and mice to radio frequency radiation for nine hours daily over two years. Rats were exposed in the womb, while mice started at 5-6 weeks old. They lived in chambers with RF fields of 900 and 1,900 MHz. The study found that radiation exposure is linked to tumor development in the hearts, brains, and adrenal glands of male rats.
