(3) Declared pregnant women likely to receive during the entire pregnancy, from radiation sources external to the body, a deep dose equivalent in excess of 0.1 rem (1 mSv);
2 All of the occupational doses in § 20.1201 continue to be applicable to the declared pregnant worker as long as the embryo/fetus dose limit is not exceeded.
Individuals entering a high or very high radiation area.
(b) Each licensee shall monitor (see § 20.1204) the occupational intake of radioactive material by and assess the committed effective dose equivalent to -
Adults likely to receive, in 1 year, an intake in excess of 10 percent of the applicable ALI(s) in table 1, columns 1 and 2, of appendix B to §§ 20.1001-20.2402;
Minors likely to receive, in 1 year, a committed effective dose equivalent in excess of 0.1 rem (1 mSv); and
(3) Declared pregnant women likely to receive, during the entire pregnancy, a committed effective dose equivalent in excess of 0.1 rem (1 mSv).

The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 10 CFR Part 20 after this date.
The U.S. Nuclear Regulatory Commission (NRC) is amending its regulations to make miscellaneous corrections. These changes include renaming the Office of Information Services, renaming the Computer Security Office and removing it as a standalone office, capitalizing the words Tribe, Tribes, and Tribal, correcting a Web site address, correcting a misspelling, removing a submission requirement, correcting an email address, correcting a room number, removing a Federal Register notice requirement, and adding missing information collection references. This document is necessary to inform the public of these non-substantive changes to the NRC's regulations.
The U.S. Nuclear Regulatory Commission (NRC) published a final rule in the Federal Register on September 9, 2015, that amended its regulations to better adhere to the Office of Federal Register's (OFR) guidance for formatting authority citations. In addition, the final rule corrected typographical errors and made other non-substantive corrections to the NRC's authority citations. The final rule contained incorrect punctuation and spacing, one incorrect reference, and omitted two references. This document makes additional corrections to NRC's authority citations.
On March 26, 2015, the U.S. Nuclear Regulatory Commission (NRC) requested public comment on a proposed rule that would amend its regulations that govern low-level radioactive waste (LLRW) disposal facilities. The proposed rule would require new and revised site-specific technical analyses, permit the development of site-specific criteria for LLRW acceptance based on the results of those analyses, facilitate implementation, and better align the requirements with current health and safety standards. Also on March 26, 2015, the NRC requested comment on draft guidance to address the implementation of the proposed regulations (NUREG-2175, “Guidance for Conducting Technical Analyses for 10 CFR part 61”). The public comment period for the proposed rule and draft guidance closed on July 24, 2015. The NRC is reopening the public comment periods for the proposed rule and draft guidance to allow more time for members of the public to develop and submit their comments.
On June 23, 2015, the U.S. Nuclear Regulatory Commission (NRC) requested public comment on three petitions for rulemaking (PRM) requesting that the NRC amend its “Standards for Protection Against Radiation” regulations and change the basis of those regulations from the linear no-threshold model of radiation protection to the radiation hormesis model. The public comment period was originally scheduled to close on September 8, 2015. The NRC is extending the public comment period to allow more time for members of the public to develop and submit their comments.
The U.S. Nuclear Regulatory Commission (NRC) has received three petitions for rulemaking (PRM) requesting that the NRC amend its “Standards for Protection Against Radiation” regulations and change the basis of those regulations from the Linear No-Threshold (LNT) model of radiation protection to the radiation hormesis model. The radiation hormesis model provides that exposure of the human body to low levels of ionizing radiation is beneficial and protects the human body against deleterious effects of high levels of radiation. Whereas, the LNT model provides that radiation is always considered harmful, there is no safety threshold, and biological damage caused by ionizing radiation (essentially the cancer risk) is directly proportional to the amount of radiation exposure to the human body (response linearity). The petitions were submitted by Carol S. Marcus, Mark L. Miller, and Mohan Doss (the petitioners), dated February 9, 2015, February 13, 2015, and February 24, 2015, respectively. These petitions were docketed by the NRC on February 20, 2015, February 27, 2015, and March 16, 2015, and have been assigned Docket Numbers. PRM-20-28, PRM-20-29, and PRM-20-30, respectively. The NRC is examining the issues raised in these petitions to determine whether they should be considered in rulemaking. The NRC is requesting public comments on these petitions for rulemaking.
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations that govern low-level radioactive waste (LLRW) disposal facilities to require new and revised site-specific technical analyses, to permit the development of site-specific criteria for LLRW acceptance based on the results of these analyses, to facilitate implementation, and to better align the requirements with current health and safety standards. This proposed rule would affect LLRW disposal licensees or license applicants that are regulated by the NRC or the Agreement States.
On July 25, 2014, the U.S. Nuclear Regulatory Commission (NRC) published for comment an advance notice of proposed rulemaking (ANPR) to obtain input from members of the public on the development of a draft regulatory basis. The draft regulatory basis would identify potential changes to the NRC's current radiation protection regulations. The potential changes, if implemented, would achieve a closer alignment between the NRC's radiation protection regulations and the recommendations of the International Commission on Radiological Protection (ICRP) contained in ICRP Publication 103 (2007). The NRC is extending the comment period for the ANPR to provide additional time for members of the public to develop and submit their comments.
