Problem
An imaging technique requires electromagnetic radiation that
(i) can penetrate soft tissue to reach bones,
(ii) carries enough energy per photon to darken a photographic film, but
(iii) is less energetic than γ-rays to minimise nuclear damage.
Which radiation best satisfies these conditions?
(a) Ultraviolet rays
(b) X-rays
(c) Gamma rays
(d) Microwaves
