Question 24
H

An X-ray image shows bones clearly but shows soft organs, such as the stomach, very poorly.

Which statement explains this?

[1]
A

Soft organs reflect all of the X-rays, so none reach the detector behind them

B

X-rays travel more slowly through soft organs, so they reach the detector too late

C

Soft organs absorb all of the X-rays, so the whole area looks the same as bone

D

Soft organs absorb similar small amounts of X-rays, so there is little contrast
