DECONTAMINATION OF RADIONUCLIDE CONTAMINATED SURFACES USING ABRASIVE REMOVAL TECHNIQUES (SCABBLING)

摘要

This paper will both summarize the regulatory requirements (e.g.: NRC, EPA, state)surrounding radiological decontamination of porous surfaces using abrasive removaltechniques (scabbling), and present a mathematical model used for estimation ofparticulate dust emissions during scabbling activities. A case study example ofdecontamination for free release employed at a Fortune 500 Facility to meet NRCRelease for Unrestricted Use Standards will also be discussed.
