What are the potential effects on tissue from high doses of radiation during examinations?

High doses of radiation can result in permanent damage to tissues. This is primarily due to the ionizing nature of the radiation, which can cause alterations at the cellular level. When tissues are exposed to high radiation doses, the DNA inside the cells may be damaged, leading to potential cellular death or mutations. If enough cells are affected, this can result in long-term consequences such as scarring, organ dysfunction, or an increased risk of cancer over time.

Furthermore, the severity of the damage is often dose-dependent; higher exposures are associated with a greater likelihood of irreparable harm to tissues. This is particularly concerning in sensitive areas such as the bone marrow, skin, and reproductive organs. On the other hand, temporary swelling or immediate sensitivity may occur with lower doses or could be localized effects, while some exposure levels might not produce any noticeable effects at all in certain scenarios. However, high doses unequivocally carry the risk of leading to permanent damage in the affected tissues.
