Type of Damage
Prospects for DNA Repair
| Single strand break in the DNA||Can usually be repaired and normal cell function restored|
| Breaks in both DNA strands||Usually damage is to severe for repair. The cell dies.|
| Chemical change or mutation||Cannot be repaired. Cancer may result or a mutated offspring if this occurs in a sperm or egg cell |
|*Cells (such as those contained in the skin, eyes and blood-forming organs (BFO)) that reproduce rapidly are the most susceptible to damage because they cannot repair themselves easily while replicating. Acceptable radiation doses are usually given separately for these organs.
