A change in the DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals is called mutation.
Irritation or damage to the skin caused by radiation exposure: two examples are sun burn and beta burns.
Ultraviolet radiation that comes from the sun.
This must refer to radiation sickness, which is caused by exposure to high doses of radiation. It can begin with minor bleeding and more exposure will cause hair to fall out and failure of organs.
Mutation
A precancerous lesion is a preliminary stage of skin cancer caused by genetics, and exposure to x-ray radiation or UV radiation.
A burn on the skin caused by excessive exposure to the sun or other sources of ultraviolet-A and -B radiation.
A change in DNA sequence caused by a mistake is called a mutation.
A person may accumulate toxic amounts of a chemical in his or her body through daily exposure to the chemicals. Common routes of exposure include
Both ultraviolet radiation and damaging oxygen radicals caused by sun exposure may damage cells, particularly their DNA.
It is estimated that up to 90% of skin cancer cases are caused by exposure to ultraviolet (UV) radiation from the sun. UV radiation damages the DNA in skin cells, increasing the risk of skin cancer development. It is important to protect the skin from sun exposure to reduce the risk of developing skin cancer.
Tanning is the darkening of skin color. It is caused by either a prolonged exposure to ultra violet radiation or by using artificial sources.
