Bacterial or Viral infections are a couple of ways cells are damaged or killed.
Trich won't damage your cells.
Melanin is the pigmentation that protect cells from solar damage.
Most genetic damage in cells does not affect offspring because it occurs in somatic cells, which are not involved in reproduction. However, if genetic damage occurs in germ cells (sperm or eggs), it can be passed on to offspring.
they can damage your cells because they can live inside your body
The red blood cells
Rapidly dividing cells like stem cells, bone marrow cells, and intestinal cells are most sensitive to radiation damage due to their high rate of cell division, making them more susceptible to DNA damage. Cells in the skin and mucous membranes are also highly sensitive to radiation.
Because there is less genetic damage to the cells when they are cold.
Cytokines
Radiation exposure causes damage to the cells of your body, which can mutate them. Mutated cells are sometimes referred to as cancer cells, and thus radiation can give you cancer. There are different effects from different kinds of radiation, but mutating cells is the basic form of damage that radiation does.
