All of the following cell types can be sensitive to ionizing radiation damage: Stem cells: can be more sensitive because they are actively dividing. Rapidly dividing cells: such as those in the skin, digestive tract, and bone marrow. Cancer cells: due to their increased rate of cell division compared to normal cells.
Cells that rapidly divide are most sensitive to ionizing radiation damage, including stem cells, progenitor cells, and cells of the gastrointestinal tract, bone marrow, and skin. These cells have higher metabolic activity and are less able to repair damaged DNA compared to more differentiated 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.
Bone marrow cells divide rapidly and are susceptible to the effects of radiation.
Cells that do not have a nucleus
Rapidly dividing cells, such as those in the bone marrow, gastrointestinal tract, and hair follicles, are the most sensitive to radiation damage. These cells are actively undergoing mitosis and are therefore more susceptible to the effects of radiation.
Rapidly dividing cells, such as those found in the bone marrow, gastrointestinal tract, and hair follicles, are most sensitive to ionizing radiation due to their high rate of proliferation. This is because ionizing radiation primarily affects cells during the division process, when the DNA is most vulnerable to damage.
Mature red blood cells are least sensitive to ionizing radiation damage because they do not possess a nucleus, limiting their ability to repair DNA damage caused by radiation exposure. This makes them less vulnerable to the harmful effects of ionizing radiation compared to other cell types like stem cells or rapidly dividing cells.
The ones with the shortest (normal) lifespans - like skin & the lining of the gut.
Cells that are actively dividing are most sensitive to radiation damage.
Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
so hair cells divide really fast too. That's why when treating cancer (rapidly dividing cells) you may lose your hair. Because the treatment like radiation or chemo kills all rapidly dividing cells
