Which of the following fetal doses is associated with a high risk of developing congenital malformations and other serious outcomes?

A fetal dose of more than 10,000 mRem is associated with a significantly elevated risk of congenital malformations and other serious health outcomes. This level of exposure is well above the thresholds typically considered safe during pregnancy. Research suggests that doses in this range can result in a higher incidence of developmental issues, including physical malformations and neurological impairments. The potential for serious outcomes increases as the dose escalates, making it critical to minimize radiation exposure to the fetus whenever possible.

On the other hand, doses below this threshold, such as those in the ranges of less than 1000 mRem or 0 - 500 mRem, are generally considered to carry minimal risk of detrimental effects on fetal development. While any exposure should still be justified and minimized, it is the higher ranges that pose the most significant concern.
