10、n the operation of a uranium conversion facility there isa potential for both chemical and radiological exposure toemployees,the public,and the environment.This potential isreduced by implementation of the practices described in thisguide.The development of this guide,as part of soundmanagement prac
11、tice,provides a means for ensuring consis-tency between facilities,and documentation and formalizationof existing practices.4.4 To establish a quality assurance program for a uraniumconversion facility,the practices in use should be evaluatedagainst the recommended practices of this guide.Existingpr
