The Inquiry made 12 recommendations to the NSW Government in its report of September 2008. The Government responded to the Inquiry in March 2009, largely supporting the recommendations.
Recommendation 3 was that a gamma radiation survey be carried out of all properties in Nelson Parade and properties on other nearby streets.
Recommendation 6 was that the results of the survey be made available to the community.
During the investigation it became evident that there were two separate causes of gamma radiation in the vicinity of Nelson Parade. These two causes were dealt with in separate reports. The survey reports were completed in June 2009 and following consultation with residents and Hunters Hill Council, were released publicly.
The report into 7–9 Nelson Parade investigated radiological contamination from the former uranium processing plant, which was the subject of the Parliamentary Inquiry.
The report into Kelly's Bush investigated radiological contamination from the former tin smelter. It found that tin slag contained trace levels of thorium, a naturally occurring radioactive material. Tin slag has been used as fill in parts of Kelly's Bush and as road-base beneath some roads in Hunters Hill.
The investigations found that levels of radiation on properties surrounding 7-9 Nelson Parade, at Kelly's Bush and in nearby areas of Hunters Hill were below relevant national and international guidelines for the protection of health and therefore remediation was not warranted.
Further information on radiation can be obtained from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).
