Radiation exposure during pregnancy can lead to various health risks for the developing fetus, and one of the potential effects is low birth weight. This can occur due to several factors, such as disruption of normal cellular growth and development caused by radiation. The exposure can hinder the placenta’s ability to provide adequate nutrients and oxygen to the fetus, resulting in a lower birth weight compared to infants not exposed to radiation.

Low birth weight can be associated with a range of future health issues, including compromised immune function and increased risk of developmental delays. Monitoring and managing radiation exposure during pregnancy is, therefore, critical to protecting both maternal and fetal health.

The other options do not accurately reflect the known effects of radiation exposure during pregnancy. Increased height, enhanced immune system, and improved cognitive function are not recognized outcomes associated with radiation exposure in utero. In fact, proper prenatal care often emphasizes minimizing radiation exposure to mitigate risks to the developing child.
