Technical Memoranda 47

The Alligator Rivers Region Research Institute (arrri) undertakes research into the effects on the environment of uranium mining operations in the Alligator Rivers Region of the Northern Territory. The Environmental Radioactivity section of arrri carries out research related to the protection of humans from radiological hazard. This work has required the development of a number of techniques for radionuclide measurement and their application to studies of the transport of radionuclides through the environment.
In April 1985 a workshop entitled 'Measurement of Long-lived Environmental Radionuclides' was held in Sydney, New South Wales. Four papers were presented by officers of arrri, covering the topics of gamma spectrometry, alpha spectrometry and gross alpha counting, and were published in the workshop proceedings. In September 1990 a second workshop, entitled 'Environmental Radiochemistry and Radionuclide Measurement', was held in Adelaide, South Australia. As an outgrowth of these workshops, a formal association of scientists involved in environmental radioactivity studies in the South Pacific region has been formed. Called the South Pacific Environmental Radioactivity Association (spera), this organisation has now held workshops in Tahiti (1991), Dunedin (1992) and Canberra (1994), with the next meeting scheduled for Darwin in 1996.
Five papers presented by staff of arrri at the 1990 workshop in Adelaide have been prepared in written form. They are being presented here as a Technical memorandum in the Supervising Scientist's publication series to ensure that the information contained in them is given more widespread distribution.
