Question

how do radiography and fluoroscopy compare?
neither technique increases the risk of developing cancer.
radiography can monitor a process, but fluoroscopy forms a single image.
each technique uses electromagnetic waves.
radiography uses ionizing radiation, but fluoroscopy does not.

Explanation:

Both radiography and fluoroscopy use electromagnetic waves (X - rays, a type of electromagnetic wave) for imaging. Radiography forms a single - static image, while fluoroscopy can be used to monitor a process. Both involve ionizing radiation and increase the risk of cancer to some extent.

Answer:

C. Each technique uses electromagnetic waves.
