Former uranium processing site at Hunter's Hill

In 2008 a Parliamentary Inquiry was held into the former uranium processing site at Hunter's Hill, Sydney. 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. The survey reports were completed in June 2009 and following consultation with residents and Hunter's Hill Council, are now released publicly - see below.

The investigations found that levels of radiation on properties surrounding 7-9 Nelson Parade, at Kelly's Bush and in nearby areas of Hunter's Hill were below relevant national and international guidelines for the protection of health and therefore remediation was not warranted. During the investigation it became evident that there were two separate causes of gamma radiation in the vicinity of Nelson Parade. These two causes are dealt with in separate reports.

The report into Nelson Parade investigates radiological contamination from the former uranium processing plant at 7-9 Nelson Parade. This is the area that was the subject of the parliamentary inquiry.

The report into Kelly's Bush investigates radiological contamination from the former tin smelter at Kelly's Bush. The report found that tin slag contains trace levels of thorium, a naturally occurring radioactive material. Tin slag has been used as fill in parts of Kelly's Bush and as roadbase beneath some roads in Hunter's Hill.

Further information on radiation can be obtained from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).
