What is the primary mechanism by which diagnostic x-ray photons damage cellular DNA?
A
Direct ionization of the DNA molecule by the x-ray photon itself
B
Indirect action — the photon ionizes water molecules within the cell, producing highly reactive free radicals that then chemically damage DNA
C
Photoelectric absorption of the photon by calcium atoms in the cell nucleus
D
Compton scatter photons directly cleaving the phosphodiester backbone of DNA strands
