    Effects on the surrounding population of postulated major accidents at the AAEC Research Establishment
    (Australian Atomic Energy Commission, 1972-11) Button, JCE; Carruthers, E; Cook, JE; Crancher, DW; Davy, DR
    The consequences of accidents in specific facilities at the Research Establishment are examined in terms of possible exposure of persons living around Lucas Heights to release airborne radioactive and toxic materials. In the case of radioactive materials both individual and population doses are estimated the latter over a range of meteorological conditions. Using currently available data on the risk of development of adverse effects in irradiated populations further estimates are made of the possible number of cases of such effects in the local population.

    Emergency reference levels
    (Australian Atomic Energy Commission, 1973-08) Cook, JE
    The risks (probabilities of subsequently developing cancer) associated with UK and US recommendations on dose limits for specific radiological emergency situations are examined and used as a basis for recommending levels of risk at which consideration should be given to specific countermeasures. These emergency reference levels for risk provide a generalised means of deriving consistent emergency reference levels for dose and other hazard parameters applicable to any radiological emergency situation.

    Environmental survey at the A.A.E.C. Research Establishment, Lucas Heights : results for 1968.
    (Australian Atomic Energy Commission, 1970-07) Cook, JE; Dudaitis, A
    This report is a second supplement to AAEC/151 'Results of the Lucas Heights Biological Survey, December 1959 - December 1964;. The results of the environmental survey during 1968 are tabulated and compared with derived maximum permissible concentrations appropriate to the local environment of the A.A.E.C Research Establishment. Radioisotope concentrations attributable to Research Establishment operations were less than one thousandth of the derived maximum permissible concentrations and a calculation of possible doses to members of the local population gives results less than one tenth of one percent of the natural radiation background.

    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 A.A.E.C. Research Establishment, Lucas Heights: results for 1969.
    (Australian Atomic Energy Commission, 1970-11) Cook, JE; Dudaitis, A
    This third supplement to AAEC/E151, 'Results of the Lucas Heights Biological Survey, December 1959 to December 1964', tabulated the results of the environmental survey during 1969 and compares them with derived maximum permissible concentrations appropriate to the local environment. Possible doses to individual members of the local population as a result of Research Establishment operations are less than those due to weapons test fallout and much less than those due to natural radiation background.

    Estimates of radiation dose to the Australian population as a result of exposure to fallout from the French and Chinese nuclear bomb tests over the period 1964 - 1972 and assessments of the adverse effects on public health
    (Australian Atomic Energy Commission, 1973-03) Cook, JE; Combe, V
    Measurements of fallout levels in Australia up to 1971 are reviewed and used? to estimate Australian average individual dose commitments. An alternative set of numbers is given based on the most recent figures for global average dose commitments provided by the United Nations Scientific Committee on the Effects of Atomic Radiation. The two sets of numbers show reasonable agreement; the larger are adopted for use in estimating adverse effects. The contribution of the French and Chinese weapons tests relative to that from all tests is derived by inspection and extrapolation where necessary of data on the injection of strontium-90 into the northern and southern hemispheres and its subsequent deposition as a function of time. The risk data reviewed and summarised in the 1972 UNSCEAR and BEIR reports are used to derive estimates of adverse effects. It is concluded that the French and Chinese test series to the end of 1972 may be responsible over the next 20 years for up to 1.4 and 0.2 cases of cancer per year respectively in Australia. Of these cases, 0.25 per year would be leukaemia, 0.75 per year thyroid cancer and 0.6 per year all other forms. Available evidence on the mutagenic effects of radiation suggests that the total number of cases of severe genetic disease produced may be of the same order as the total number of cases of cancer, with the former spread over many generations whereas the latter are not.

    Site emergency releases and site emergency stocks - recommended values for use at the research establishment
    (Australian Atomic Energy Commission, 1974-03) Cook, JE
    Figures are given for the quantities of hazardous materials which, if released to atmosphere or if involved in an accident capable of leading to a release to atmosphere at the Australian Atomic Energy Commission Research Establishment, Lucas Heights, are the minimum amounts which could give rise to a situation requiring appraisal by the Site Emergency Organisation. Such a situation is defined as one in which potential involuntary exposures of individuals to radiation and radioactive materials may involve a subsequent risk to the exposed individual of long term adverse somatic effects (e.g. carcinogenesis) in excess of 10-4. The circumstances of an accident involving more than a site emergency stock must be investigated immediately to evaluate actual risks and to initiate emergency action if necessary. The dependence of such an evaluation on the physical and chemical forms of the material, its containment and prevailing weather conditions are described in general terms.
