The table above lists the wavelength range, frequency range, possible uses, and hazards of the seven types of electromagnetic radiation. Which type of radiation helps doctors image the interior of the human body but also causes cell damage? A.
microwave
B.
infrared
C.
radio wave
D.
X-ray

I think it's D caz X-ray scans can diagnose possibly life-threatening conditions such as blocked blood vessels, bone cancer, and infections. However, x-rays produce ionizing radiation—a form of radiation that has the potential to harm living tissue. However, the risk of developing cancer from radiation exposure is generally small.
