Lessons Learned in Implementation of Radiological Investigations of Small-Scale Sites in Port Hope, Ontario

Abstract

The Port Hope Area Initiative is a $1.28 billion project for the remediation of low-level radioactive waste resulting from the operation of Eldorado Nuclear Limited and its private-sector predecessors between 1932 and 1988 in Port Hope and Port Granby, Ontario. Included in the project is the investigation of all 4,800 privately and publicly owned properties in Port Hope in order to identify and remediate an estimated 375 properties containing LLRW exceeding clean- up criteria. This paper discusses the progress of the investigations, the development of clean-up criteria, methodologies used to identify historic LLRW, and lessons learned to date.
