Title 310 - Oklahoma State Department of Health
Chapter 281 - Medical Marijuana Regulations [Revoked]
Subchapter 9 - Standards for Protection Against Radiation
Section 310:281-9-40 - Exposure to pregnant employees

(1) If a woman chooses not to declare pregnancy the occupational dose limits specified in 310:281-9-2(a).

(2) The permittee 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 310:281-9-40(a). The National Council on Radiation Protection and Measurement in NCRP Report No. 91 "Recommendations on Limits for Exposure to Ionizing Radiation" (June 1, 1987) states that no more than 0.05 rem (0.5 mSv) to the embryo/fetus be received in any one month will be adopted.

(3) If by the time the woman declares pregnancy the permittee the DE to the embryo/fetus has exceeded 0.45 rem (4.5 mSv), the permittee is in compliance with 310:281-9-40(a), if the additional DE to the Embryo/fetus does not exceed 0.05 rem (0.5 mSv) during the remainder of the pregnancy.

(4) The DE to an embryo/fetus shall be taken as the DE that is most representative of the DE to the embryo/fetus from external radiation. The DE from the mother's lower torso region will be used.

(5) If multiple measurements have been made, assignment of the DDE for the declared pregnant woman for the personal monitoring device that is most representative of the DE to the embryo/fetus shall be the DE to the embryo/fetus. Assignment of the highest DDE for the declared woman to the embryo/fetus is not required unless that dose is also the most representative DDE for the region of the embryo/fetus.

(6) If multiple measurements have not been made, assignment of the highest DDE for the declared pregnant woman shall be the embryo/fetus.
