Abstract
In ICRP Publication 60 (The Recommendations of the Commission-1990), the Commission has recommended that, once pregnancy has been declared, the equivalent dose limit to the pregnant worker should be 2 mSv for the surface of her abdomen during the remainder of the pregnancy. In addition, the Commission has recommended that the fetus should be afforded the same broad level of protection as required for members of the public. The verifications of whether the Commission's recommendations on the occupational exposure of pregnant women can be ensured under their working conditions are carried out.
From the results, it seems to be unsuitable to accept the recommendations. It is proposed that external exposure for pregnant workers estimates ambient dose equivalent, H (10) on the surfaces of their abdomens and the dose limit to the pregnant women should be 1 mSv during the remainder of the pregnancy.
