the sum of:
(a) The deep dose equivalent to
the declared pregnant woman; and

radionuclides in the embryo/fetus and radionuclides in the declared pregnant
woman.

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.
