Radiometry

Gawler Craton Airborne Survey Magnetic Radiometric and DEM Merge, SA, 2017-2019 - Radiometrics - Uranium Equivalent Ground Concentration  (133.4069 E, -30.0443 S) Gamma Max Lake (Flight Path Bubble Map) - total gamma counts per second Gamma Spectrum - GCAS - NORM baseline (red), dry lake (blue), Maralinga (yellow)

  Mineral sand stockpiles from 50 years ago are being recovered by this company. One stockpile is just north of the Hawks Nest golf links. It is visible in radiometric imagery. National Parks seem to be happy with the removal of this radioactive material. It has also been removed from Bundjalung NP. China Australia Mining was the company's business name from 2021-08-21. Other business names include Greencoast Environmental Rehabilitation. Their official company name changed on 2007-06-21 to China Australia Mining Pty Ltd. The company had used this name up until 2021-08-24. This Australian proprietary company was previously located in SA 5067 (from 2014-01-18 to 2014-09-23), SA 5067 (from 2007-06-21 to 2014-01-18). AUSGIN imagery identifies Uranium and Thorium minerals in rocks and other deposits, including mineral sand mining waste. It identifies multiple near-beach sites in need of environmental restoration and this is occurring, particularly in New South Wales. The radio-mineral...

  Radiometric imagery withheld from public at Evetts Field and Lake Reynolds, SA.  Recent high-detailed radiometric imagery  from the Gawler Craton Airborne Survey (GCAS) is not available for the area surrounding Evetts Field. A close examination of the data file shows that this area was over-flown, but the data has been removed. This may be to conceal the radiometry of the shed containing the 10,000 drums of CSIRO waste from processing Uranium and Thorium ores at Fishermans Bend . It may also conceal the old HIFAR core of the Lucas Heights reactor. A small sample of these drums have been previously analyzed by CSIRO . The condition of these drums is deteriorating, and the Federal Government wants to move them to an interim intermediate-level waste storage facility at Kimba, SA. Nuclear waste – domestic Australian issues

The Olympic Dam Uranium mine in South Australia is quite conspicuous in airborne radiometric imagery. It can be viewed on the Geophysical Archive Data Delivery System ( GADDS ).
