[en] Radioactive tracking techniques are being used to aid the investigation and control of termites. Studies include work related to the restoration of historic buildings when the damage inflicted on the timbers needs to be determined with minimum disturbance to the building. Another investigation has been the radioactive monitoring of pest-control techniques. Scandium-46, lanthanum-140 and gold-198 have been used in different investigations

[en] A new process for the extraction of uranium has been developed and applied commercially at the uranium mill at Nabarlek in the Northern Territory. The process uses Caro's acid rather than pyrolusite as the oxidizing agent. The process has both economic and environmental advantages

[en] Migration naturally occurring radioactive substances leached by water out of Australian uranium deposits is being investigated by scientists from the Australian Atomic Energy Commission. These investigations help predict the long-term consequences of leaching of material from underground repositories of radioactive wastes from nuclear power stations. Rates of migration of naturally radioactive substances provide yardsticks by which to access the migration rates of man-made radioactive substances

[en] Between 1953 and 1971 uranium was mined at Rum Jungle in the Northern Territory, Australia. As a result of the mining operations the Finniss river system near the mines became polluted. This pollution was related to the occurrence of sulphur as pyrites in overburden heaps. A rehabilitation program for the Rum Jungle area is planned

[en] The development and evaluation of Synroc for radioactive waste disposal is discussed. In irradiation tests (equivalent to storage for 10,000 years) Synroc did not crack and expanded by an amount too slight to cause problems. Distortion of the crystals was slight. Synroc is significantly more resistant to attack by very hot water than glass. The manufacturing process is outlined

[en] A tracer technique was used to investigate the movement of chemical waste that is dumped in Bass Strait from a paint pigment factory in northern Tasmania. A gold-198 labelled ferric hydroxide floc was mixed with the waste. It was found that during relatively calm weather the waste accumulates on the sea bed near the outfall, but that during storms the accumulated waste can be transported shorewards by wind driven sea currents

[en] AAEC scientists have developed a new radiopharmaceutical of commerical potential which can be applied to the diagnosis of diseases involving abnormal functioning of the liver, bile duct or gall bladder. It is technetium-bromo-BIMIDA. Other investigations include the enhancement of images from gallium-67 citrate in tumours and the interaction between iron dextran and technetium-pyro-phosphate
