-
X-rays used freely before radiation dangers were known. Some physicians unknowingly imaged pregnant women. Later studies revealed risk of embryonic and fetal damage. -
Edison’s assistant died from radiation-induced cancer. First recognized radiation fatality in the U.S. Sparked initial safety concerns in medical imaging. -
Hermann Muller showed X-rays caused heritable mutations. First link between radiation and DNA alteration. Raised fears about fertility and birth defects in humans. -
Pregnant women exposed to radiation from atomic bombs. Reports of miscarriages and birth defects among survivors. Became foundation for fetal-dose research and limits. -
Introduced to protect testes and ovaries during X-rays. Aimed to reduce genetic and fertility damage. Adopted as global safety standard in diagnostic imaging. -
Birth defect crisis showed vulnerability of unborn children. Inspired strict medical-imaging protocols for pregnancy. Reinforced ALARA principle: “As Low As Reasonably Achievable.”
-
Fallout reached pregnant populations across Europe. Increased rates of miscarriage and developmental issues. Highlighted intergenerational impact of radiation exposure. -
Fetal dose limit set at 5 mSv during pregnancy. Facilities required to provide lead shielding and monitoring. Ensured workplace safety for technologists and nurses. -
Pregnant women prioritized in evacuation plans. Widespread public fear of infertility and birth effects. Triggered global reviews of radiologic safety policies. -
NCRP recommended stopping routine gonadal shielding. New equipment minimizes scatter and dose automatically. Marks shift toward technology-based radiation protection. -
Imaging software now calculates fetal dose automatically. Integrates radiation data into patient safety records. Reflects precision and accountability in modern radiology.
