Which of the following statements regarding the biological effect mechanisms of the direct theory is false?

Question

A) Most dental x-ray photons pass through the cell, causing no damage.
B) X-ray photons may collide with important cell chemicals and break them apart.
C) Ionization can cause critical damage to large molecules.
D) Irradiated cells cannot be repaired.

Answer 1

D
Explanation: A) Healthy cells can repair minor damage caused by ionization. Moreover, the body contains so many cells that the loss of a single cell or a small cluster of cells would be unlikely to have any obvious effect.
B) Healthy cells can repair minor damage caused by ionization. Moreover, the body contains so many cells that the loss of a single cell or a small cluster of cells would be unlikely to have any obvious effect.
