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:

Radiography and fluoroscopy are both imaging techniques that rely on electromagnetic - wave based ionizing radiation. Both carry a small risk of cancer due to ionizing radiation exposure. Radiography creates a single - static image, while fluoroscopy can provide real - time imaging to monitor a process.

Answer:

C. Each technique uses electromagnetic waves.
