What theory of radiation damage to cells results from free radicals combining to form toxins such as hydrogen peroxide?

A) Primary
B) Secondary
C) Indirect
D) Direct

C
Explanation: A) Indirect theory is based on the assumption that radiation can cause chemical damage to the cell by ionizing the water within it. Ionization dissociates water into hydrogen and hydroxyl radicals that can form new chemicals such as hydrogen peroxide that act as toxins (poisons) to the body, causing cellular dysfunction.
