1219-AB97 202210 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 1219 Mine Safety and Health Administration MSHA 1200 Department of Labor DOL Radon Progeny

The Mine Safety and Health Administration proposes to amend existing standards to address the issues related to radon progeny for metal and nonmetal miners.  Under the existing standards, metal and nonmetal miners’ exposures to radon are limited to 1.0 working level (WL) in active workings, and 4 working level month (WLM) in any calendar year.  The proposed rule would reduce radiation exposure in all underground metal and nonmetal mines to protect miners from developing radiation-induced cancer.
