A member asked:
Why does a high amount of radiation in ct scan not cause more damage than a lower amount of natural radiation over two year time? doesn't the natural smaller amount of damage overtime give cells a chance to fix damage more than a ct scan?

CT radiation ?'s: The level of radiation exposure is cumulative over time (hence the use of radiation detection badges in employees doing the various radiation imaging), so a higher exposure (as in CT scans) over time can cause mutations in the cell DNA which can become cancerous.
