Abstract

This report details results of integrated radon measurements taken in and around five houses at Alice Springs. Radon concentrations were measured in reticulated water supplies, household rooms and outdoor air. The reticulated water supply and bathroom air of two houses in Santa Teresa were also measured. The possible significance of the water supply as a source of indoor atmospheric radon is discussed. Recommendations for further reticulated water supplies discussed. sampling and implications for in the Northern Territory are discussed.

I I I I I I I I I I I I I I I I I I I I Shown in tlgure 3{a} is the variation in ratio of raCon-222 to total radon against radon-222 measured in Alice Springs. A ratio of one indicates the presence of only the isotope radon-222. The distribution suggests that radon-222 is the principal isotope and that the thoron isotope makes a negligible contribution to indoor radon concentrations in Alice Springs. In only one case , the laundry of house 3 is there any statistical difference at the 95 percent confidence level between rooms within a house. Ignoring the laundry of house threer no significant difference between houses in Alice Springs is observ_ed. The radon concentrations represent an integrated measurement over one hundred days and coincide with the transition period between winter and summer in Central Australia. Listed in table 3 (ii) are the average monthly maximum and minimum temperatures experienced in Alice Springs during the months August to November 1984. Included for comparison are the long term monthly averages Table 3 (ii) ALICE SPRIRGS MAXIMUM & MINIMUM AVERAGE MONTHLY TEMPERATURES 1984 { c ).
