    The Alligator Rivers area fact finding study: four AAEC reports
    (Australian Atomic Energy Commission, 1974-06) Conway, NF; Davy, DR; Giles, MS; Newton, PJF; Pollard, DA
    The work described in this series of reports is part of the Joint Government-Industry Fact Finding Study carried out in the 'Uranium Province' of the Alligator Rivers Area, Northern Territory, during 1971—73. The primary objective was to determine the sensitivity of the existing environment to the range of potential pollutants arising from a uranium extractive industry. A comprehensive ichthyography is given of species collected in the area. Results are reported of experimental and bioassay studies on selected flora and fauna exposed to heavy metals, raffinate and Alamine-336. Studies are also recorded on the chemical and radiological qualities of natural waters, the solubility of uranium in sediments, and the fate of dissolved trace elements in the drainage systems. The radiological aspects of the area are discussed with specific reference to exposure routes, bit ogical concentration factors, and the significance of natural and man made changes in levels of radiation to man and other biota in the region. Radon levels in costeans, core-sheds and bore water are recorded and discussed.

    Environmental survey at Lucas Heights Research Laboratories, 1984.
    (Australian Atomic Energy Commission, 1986-12) Giles, MS; Dudaitis, A
    Results are presented of the environmental survey conducted in the neighbourhood of the Lucas Heights Research Laboratories during 1984. These results are satisfactory. No radioactivity which could have originated from these laboratories was found in samples collected from possible human food chains. All low-level liquid and gaseous waste discharges were within authorised limits. The maximum possible annual dose to the general public from airborne waste discharges during this period is estimated to be less than 0.01 millisieverts which is one per cent of the limit for long-term exposure that is recommended by the National Health and Medical Research Council.

    Environmental survey at the A.A.E.C. Research Establishment, Lucas Heights: results for 1965, 1966 and 1967
    (Australian Atomic Energy Commission, 1969-11) Cook, JE; Dudaitis, A; Giles, MS
    This report is a supplement to AAEC/E151. Results of the Lucas Heights Biological Survey, December 1959 - December 1964, and gives the results of environmental surveys for 1965, 1966 and 1967. They are tabulated and compared with derived maximum permissible concentrations appropriate to the local environment. Where found, concentrations of radioisotopes attributable to Research Establishment operations were generally at or below one thousandth of these derived maximum permissible concentrations and there is no indication that such operations give rise to any exposure of the local population to radiation.

    Environmental survey at the AAEC Research Establishment Lucas Heights - results for 1979
    (Australian Atomic Energy Commission, 1980-09) Giles, MS; Dudaitis, A
    This report presents the results of the environmental survey at the AAEC Research Establishment Lucas Heights during 1979. They show that the only radioactivity detected which could be of AAECRE origin and which could also be ingested by humans was due to tritium. The maximum credible dose which a member of the public could receive from this radioactivity is calculated to be one ten thousandth of the derived working limit consistent with the latest recommendations of the International Commission on Radiological Protection.

    Environmental survey at the AAEC Research Establishment, Lucas Heights - results for 1980
    (Australian Atomic Energy Commission, 1982-05) Giles, MS; Dudaitis, A
    Results are presented of the environmental survey at the AAEC Research Establishment Lucas Heights during 1980. They show that the only radioactivity detected which could be of Research Establishment origin and which could also be ingested by man was due to tritium and 60Co. The maximum credible dose which a member of the public could receive from this radioactivity is calculated to be 0.0006 of the derived working limit i.e. 3 microsieverts which is equivalent to about 0.03 per cent of the natural background.

    Results are presented of the environmental survey conducted in the neighbourhood of the Lucas Heights Research Laboratories during 1983. These results are satisfactory. No radioactivity which could have originated from these laboratories was found in samples collected from possible human food chains. All low-level liquid and gaseous waste discharges were within authorised limits. The maximum possible annual dose to the general public from airborne waste discharges during this period is estimated to be less than 0.01 millisieverts which is 1 per cent of the limit for long-term exposure that is recommended by the National Health and Medical Research Council.

    Results of the Lucas Heights biological survey December 1959 - December 1964
    (Australian Atomic Energy Commission, 1966-08) Giles, MS; Stockdale, JA
    Results of the analysis of material collected from the environment around Lucas Heights between December 1959 and December 1964 are presented. The values obtained indicate that only negligible amounts of radioactivity have been concentrated in the environment. An evaluation of hazards is presented and it is shown that the highest levels of radioactivity found would have to be increased by factors of hundreds or thousands to reach the maximum levels permitted by International Standards Organisations for safe continuous intake by members of the public.

    A study of the movement of phosphorous in the Little River Estuary, NSW
    (Australian Atomic Energy Commission, 1972-10) Giles, MS
    The estuary of the Little River, N.S.W. was mapped and measurements made of phytoplankton productivity, phosphorus content, chlorophyll 'a' content, zooplankton biomass, salinity, temperature and oxygen content. Phosphorus-32 and hydrogen-3 were injected into the estuary and the rate of movement of phosphorus-32 into the phytoplankton and zooplankton was calculated. The turnover time for phosphorus-32 in solution was approximately two hours.
