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.

How long were the rats and mice exposed to radio frequency radiation each day?

• Six hours

• Twelve hours

• Nine hours

• Three hours

At what age did the mice start being exposed to radiation?

• Immediately after birth

• 2 to 3 weeks old

• 5 to 6 weeks old

• 10 to 12 weeks old

What were the frequencies of the RF fields used in the study?

• 1,500 and 3,000 megahertz

• 500 and 1,000 megahertz

• 900 and 1,900 megahertz

• 1,200 and 2,400 megahertz

What type of chambers were the rodents kept in during the study?

• Glass enclosures

• Specially designed chambers

• Standard laboratory cages

• Open-air cages

Which organs in male rats showed tumor development due to radiation exposure?

• Stomach, intestines, and pancreas

• Lungs, liver, and kidneys

• Skin, eyes, and ears

• Hearts, brains, and adrenal glands
