Nuclear Regulatory Commission August 17, 2021 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is denying three petitions for rulemaking (PRMs), submitted by Dr. Carol S. Marcus, Mr. Mark L. Miller, Certified Health Physicist, and Dr. Mohan Doss, et al. (collectively, the petitioners) in correspondence dated February 9, 2015, February 13, 2015, and February 24, 2015, respectively. The petitioners request that the NRC amend its regulations based on what they assert is new science and evidence that contradicts the linear no- threshold (LNT) dose-effect model that serves as the basis for the NRC's radiation protection regulations. The NRC docketed these petitions on February 20, 2015, February 27, 2015, and March 16, 2015, and assigned them Docket Numbers PRM-20-28, PRM-20-29, and PRM-20-30, respectively. The NRC is denying the three petitions because they fail to present an adequate basis supporting the request to discontinue use of the LNT model. The NRC has determined that the LNT model continues to provide a sound regulatory basis for minimizing the risk of unnecessary radiation exposure to both members of the public and radiation workers. Therefore, the NRC will maintain the current dose limit requirements contained in its regulations.
