Which of the following is an example of a radiosensitive cell?

Skin cells are indeed considered radiosensitive because they are rapidly dividing cells that are more susceptible to damage from radiation exposure. The skin consists of multiple layers, with the outer layer containing continuously renewing cells that are constantly in the process of proliferation. This high turnover rate makes skin cells more vulnerable to the effects of ionizing radiation, which can cause DNA damage leading to mutations or cell death.

Understanding radiosensitivity is crucial for radiation safety and protection practices, as different tissues and cells in the body exhibit varying degrees of sensitivity based on their rate of division and specific functions. Cells that are actively dividing, such as skin cells, bone marrow cells, and cells lining the gastrointestinal tract tend to be more radiosensitive compared to cells like nerve or muscle cells, which divide less frequently and are generally more resistant to radiation damage.
