The Supervising Scientist Division measures radon progeny potential alpha energy concentration (PAEC) in air at Jabiru town and near Mudginberri community at Four Gates Road radon station.
The purpose is to provide public assurance that there is no unacceptable radiation risk via the inhalation pathway from exposure to radon progeny in air.
The graphs below show hourly radon progeny PAEC monitoring data from Jabiru town and near Mudginberri community since January 2011. Gaps in the data are due to instrument maintenance and data quality issues. Data from previous years is available in Supervising Scientist Annual Reports.
The Supervising Scientist’s interpretation of the data below is available at explanatory notes on radon and radon progeny.
