A mutation is a permanent alteration or a change in the genetic composition of an organism. Mutagen is a physical or chemical agent which brings changes in the genome of the organism. X-ray is an example of physical mutagen. X-rays are vital imaging tool used for diagnosing bone structures in humans. Exposure to high X-ray radiation levels can have effects like vomiting, skin and hair loss, bleeding. However, exposure to low X-ray radiation levels does not cause immediate health effects. Therefore, this explains the fact that small amount of a mutagen often do not have an effect on health.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
