Which type of cells shows a high rate of reproduction and is sensitive to radiation?

The type of cells that exhibit a high rate of reproduction and are sensitive to radiation are radiosensitive cells. These cells typically include those that are rapidly dividing or have a high turnover rate, such as stem cells, germ cells, and certain epithelial cells.

When exposed to radiation, these cells are more susceptible to damage because they are actively undergoing processes like mitosis, which makes them more vulnerable to the effects of radiation. The rapid reproduction and the nature of their cellular processes mean that any disruption caused by ionizing radiation can have significant consequences for their functioning and viability.

In contrast, radioresistant cells tend to have a lower turnover rate and possess mechanisms that help them repair damage from radiation exposure. Muscle cells and nerve cells are generally considered to be more differentiated and less likely to undergo frequent division, which also contributes to their relative resistance to radiation effects. Understanding the classifications of cells based on their sensitivity helps in evaluating the risks associated with radiation exposure during dental procedures and other medical treatments. This knowledge is crucial for implementing effective radiation protection practices in healthcare settings.
