The human embryo-fetus is highly radiosensitive and must be protected from excessive exposure to ionizing radiation. The maximum permissible dose equivalent for the developing embryo-fetus is set at 0.5 rem per year--the MPD level for members of the general public. Methods by which supervisory personnel can limit the fetal dose incurred by the occupational exposure of the mother are presented. It is recommended that supervisory personnel attempt to limit occupational exposure to the current non-occupational MPD levels for all x-ray technologists, thereby, insuring that the fetal dose limits are not surpassed and providing an added safety factor for personnel by keeping exposures as low as reasonably achievable.
人类胚胎-胎儿对辐射高度敏感，必须避免过度暴露于电离辐射。发育中的胚胎-胎儿的最大允许剂量当量设定为每年0.5雷姆——这也是普通公众的最大允许剂量水平。文中介绍了监督人员可用来限制母亲职业照射所导致胎儿剂量的方法。建议监督人员尽量将所有X射线技术人员的职业照射限制在当前非职业性最大允许剂量水平，从而确保不超过胎儿剂量限值，并通过使照射尽可能低至合理可行的水平，为工作人员提供额外的安全因素。
