In the context of X-ray imaging, what does exponential attenuation refer to?.
- A.The linear decrease of X-ray intensity
- B.The gradual increase of X-ray intensity
- C.The rapid decrease of X-ray intensity with thickness
- D.The constant intensity of X-rays through any material
Model answer
What a good answer should say
- The rapid decrease of X-ray intensity with thickness
Explanation
Why this works
Exponential attenuation describes how the intensity of X-rays decreases rapidly as they pass through a material, following an exponential decay model. This means that with each unit of thickness, a fixed proportion of the X-ray intensity is lost.
