Which statement is true?

Question

Quizplus · Accepted Answer

The statement that is true is D, which states that a computer emits lower energy radiation than a cell phone. This is because a computer emits non-ionizing radiation, such as radio waves and microwaves, which have lower energies than ionizing radiation emitted by cell phones, such as X-rays and gamma rays. The other statements are false. High energy electromagnetic radiation actually has very short wavelengths and is more dangerous to humans. Electromagnetic radiation with very short wavelengths, such as gamma rays and X-rays, is the most dangerous to humans because they are ionizing and can damage DNA. Cell phone radiation is non-ionizing, posing less risk to humans than ionizing radiation.
