What is the main concern regarding radiation exposure to pregnant workers?

The primary concern regarding radiation exposure to pregnant workers centers on the potential harm to the developing fetus. During pregnancy, the cells of an unborn child are rapidly dividing and are therefore particularly sensitive to radiation. Exposure can lead to various adverse outcomes, including developmental anomalies, growth retardation, and an increased risk of cancer later in life. This consideration is critical as regulatory guidelines often aim to limit radiation exposure for pregnant workers to ensure the safety of both the expectant mother and her child. The emphasis on minimizing exposure during pregnancy reflects the understanding of the unique vulnerabilities of fetal development in relation to ionizing radiation.
