Respiratory Protection and Controls To Restrict Internal Exposures

The Nuclear Regulatory Commission (NRC) is proposing to amend its regulations regarding the use of respiratory protection and other controls to restrict internal exposure to radioactive material. The proposed amendments are intended to make these regulations more consistent with the philosophy of controlling the sum of internal and external radiation exposure, reflect current guidance on respiratory protection from the American National Standards Institute (ANSI), and make the requirements less prescriptive without reducing worker protection. The proposed amendments would provide greater assurance that worker exposures will be maintained as low as is reasonably achievable (ALARA) and that recent technological advances in respiratory protection equipment and procedures are reflected in NRC regulations and are thus clearly approved for use by licensees.
