Which group is considered most sensitive to radiation exposure?

Pregnant women are considered the most sensitive group to radiation exposure due to the unique physiological conditions during pregnancy. The developing fetus is particularly susceptible to harmful effects from radiation because its cells are rapidly dividing and differentiating. This sensitivity is heightened during the first trimester when the most critical stages of organ development occur. Exposure to high levels of radiation during this period can lead to congenital abnormalities, developmental issues, or an increased risk of cancer later in life.

In addition to the fetus, pregnant women themselves may experience health risks related to radiation exposure, which can complicate both maternal and fetal health. This increased vulnerability underscores the importance of minimizing radiation exposure in this population.

While other groups, such as infants or teenagers, also exhibit sensitivities to radiation, the heightened risks during pregnancy, particularly related to fetal development, place pregnant women at the forefront in terms of sensitivity to radiation exposure.
