Outcome and program structure

Our activities are focused into a Radiation Protection and Nuclear Safety Program. This program is made up of four key strategies, and supported by whole-of-agency stakeholder engagement and enabling support strategies, to deliver our radiation protection and nuclear safety outcome for the Australian Government and to the community.

The outcomes of ARPANSA’s activities and services are measured by Key Performance Indicators (KPIs). The 2014-15 scorecard provides a snapshot view of our performance for the year. Full explanations on all measures, analysed against previous years and set targets can be found in Part 3: Report on Performance.

The tables below provide a summary of the delivery of our 2014-15 Strategic Initiatives.
