The licensee or registrant shall ensure that the dose equivalent to the
embryo/fetus during the entire pregnancy, due to occupational exposure of a
declared pregnant woman, does not exceed five mSv (0.5 rem). See Section
for recordkeeping requirements.
The licensee or registrant shall make efforts to avoid substantial variation
above a uniform monthly exposure rate to a declared pregnant woman so as to
satisfy the limit in Subsection R313-15-208(1).
The dose equivalent to an embryo/fetus is
the sum of:
(a) The deep dose equivalent to
the declared pregnant woman; and
(b) The dose equivalent resulting from
radionuclides in the embryo/fetus and radionuclides in the declared pregnant
(4) If the dose
equivalent to the embryo/fetus is found to have exceeded five mSv (0.5 rem) or
is within 0.5 mSv (0.05 rem) of this dose by the time the woman declares the
pregnancy to the licensee or registrant, the licensee or registrant shall be
deemed to be in compliance with Subsection R313-15-208(1) if the additional
dose equivalent to the embryo/fetus does not exceed 0.50 mSv (0.05 rem) during
the remainder of the pregnancy.
