Radiation Safety Advisory Council (RSAC)

The Radiation Safety Act 2016 (the Act) came in force in March 2017 to establish a framework to protect the health and safety of people and protect the environment from the harmful effects of ionising radiation while allowing for the safe and beneficial use of ionising radiation. The Act also enables New Zealand to meet its international obligations relating to radiation protection, radiation safety and security, and nuclear non-proliferation.

The Council is an advisory group established under section 80 of the Radiation Safety Act 2016 (the Act).
