International guidance documents (e.g., ICRP Publication 60 and NCRP
Publication 116*) recommend that the radiation dose to the embryo/fetus
Exposure
of a pregnant woman should not exceed a total of 500 mrem (10% of
normal radiation worker limit) during the gestation period. While this dose
limit exceeds the dose limit to a trained operator, pregnant workers may
want to take special precautions to reduce their exposure to radiation. For
more information see the U.S. NRC Regulatory Guide 8.13 "Instruction
Concerning Prenatal Radiation Exposure" which can be found on the
resource CD.
* The International Commission on Radiological Protection, ICRP, is an
independent Registered Charity, established to advance for the public

recommendations and guidance on all aspects of protection against ionizing
radiation.
* The National Council on Radiation Protection and Measurements
(NCRP) was chartered by the U.S. Congress in 1964 as the National
