From June 1985 to June 1988 Queensland Mines Ltd operated a semi-dry system of tailings deposition in their Nabarlek mine pit. To confirm that radon and radon daughter concentrations did not become excessive, the Company carried out an intensive radon/radon daughter monitoring program. This report summarises the data from that program and also gives details of check measurements carried out by OSS.
OSS independent measurements indicate good agreement between instruments used and confirm QML's data. Dose assessments presented in this report indicate that safe working conditions were maintained and that the operations posed no hazard to members of the public.
