Sec. 835.206  Limits for the embryo/fetus.

    (a) The dose equivalent limit for the embryo/fetus from the period 
of conception to birth, as a result of occupational exposure of a 
declared pregnant worker, is 0.5 rem (0.005 sievert).
    (b) Substantial variation above a uniform exposure rate that would 
satisfy the limits provided in Sec. 835.206(a) shall be avoided.
    (c) If the dose equivalent to the embryo/fetus is determined to have 
already exceeded 0.5 rem (0.005 sievert) by the time a worker declares 
her pregnancy, the declared pregnant worker shall not be assigned to 
tasks where additional occupational exposure is likely during the 
remaining gestation period.
