    The adsorption of radioactive iodine 131 on mud
    (Australian Atomic Energy Commission, 1958-06) Ellis, WR; Gardner, ME
    The effect of potassium iodide carrier concentration on the adsorption of iodine 131, as iodide, on mud is indicated. This work was initiated to provide information for a field test on the efficiency of power station cooling ponds which was carried out in conjunction with the Electricity Commission of New South Wales.

    Labelling sewerage sludge with iodine 131.
    (Australian Atomic Energy Commission, 1958-10) Ellis, WR; Gardner, ME
    A method of labelling digested sewage sludge with iodine 131 was investigated for the South Australian Engineering and Water Supply Department, who are investigating the the possibility of disposing of sewage into the ocean, and hence are interested in tracing the movement of the sludge in the sea, in order to determine whether pollution of neighbouring beaches would occur. Satisfactory labelling of both solid and liquid phases was achieved.

    A power station cooling pond performance test with radioactive tracer iodine 131 second experiment at Maitland, N.S.W.
    (Australian Atomic Energy Commission, 1960-03) Ellis, WR; Fookes, RA; Gardner, ME; Hope, JA; Lamb, N; van Louwersen, P; Watt, JS
    A second tracer experiment to study the flow of power station cooling water in a cooling pond is described. Since the first experiment in March, 1958, the intake point had been deepened and extended into the pond in an attempt to avoid channelling. The technique used in this test was similar to that used in the first but severe weather conditions were experienced. The results showed that even a moderate wind had more effect on the flow pattern than any other factor. Some aspects of this effect were studied quantitatively. The different weather conditions experienced in the two test did not permit conclusive observations on the effects of the modified intake.

    The use of a radioactive tracer (iodine-131) in the investigation of a power station cooling pond at Maitland, N.S.W.
    (Australian Atomic Energy Commission, 1958-09) Ellis, WR; Fookes, RA; Gardner, ME; Gregory, JN; Kirkwood, JB; Lamb, GN; Watt, JS
    Radioactive iodine 131, as iodide in solution, was used to trace the flow of power station condenser water through a cooling plant. The station has rating of 20 MW and the circulating water is cooled in a pond of approximately 2 X 108 gallons capacity and 40 acres area. By labeling the warm water with 473 millicuries of iodine 131 in potassium iodide carrier, introduced at the power station outlet, and using underwater scintillation and Geiger counters, it was possible to follow quantitatively the horizontal and vertical spread of water over a period f eight days after which mixing was complete. The results gave valuable information on the pond performance under weather conditions prevailing during the test period and indicated some possibilities for improvement of performance. Further tests with iodine 131 are contemplated with modification of pond conditions
