Assessment of the radiological health risk associated with ANSTO effluent release: including the reuse of tertiary treated sewer water and sludge and the impact of effluent entering local waterways with sewer surcharge

Abstract

An analysis has been made of the radiological consequences of the release of ANSTO's aqueous discharge to the Cronulla Sewerage System. This is in response to Condition 10 of the Environmental Impact Statement supporting the Replacement Research Reactor. The analysis covers the release of effluent under normal conditions, the release of effluent as part of a sewage surge during periods of high rainfall, and the impact of the decision by Sydney Water to recycle treated sewage sludge and sewage water.
