A Radiological Dose Assessment for the Port Hope Conversion Facility

Abstract

The Port Hope Conversion Facility (PHCF) receives uranium trioxide for conversion to uranium hexafluoride (UF₆) or uranium dioxide (UO₂). The PHCF Site has a long history of industrial use.

A Radiological Dose Assessment was undertaken as part of a Site Wide Risk Assessment. This assessment took into account all possible human receptors, both workers and members of the public. This paper focuses on a radiological assessment of dose to members of the public.

The doses to members of the public from terrestrial pathways were added to the doses from aquatic pathways to obtain overall dose to receptors.

The benchmark used in the assessment is 1 mSv/y. The estimated doses related to PHCF operations are much lower than the dose limit.
