> Study of Radon from rocks and soil in the Sydney area

Two studies have been carried out so far:

• Survey of rocks and soils in the Sydney area and characterisation in terms of their Radon exhalation - see publication Lenzen M and McKenzie D R, Comparative measurements of 222Rn exhalation from rocks and soil of the Sydney area, Radiation Protection in Australasia 16 (2), 16-21, 1999

• Study on the correlation betweem indoor Radon levels and underlying Rock in the Sydney area - contact the Department for a copy of the submitted manuscript McKenzie D R, Lenzen M and Solomon S B, The correlation between exhalation from rocks and indoor concentration of 222Rn in the Sydney area, submitted to Radiation Protection in Australasia, 2001
