Environmental radioactivity annual reports

The Environmental radioactivity annual reports have reported on environmental radioactivity levels in the New Zealand and South Pacific region since 1960.

Monitoring was initially conducted for radioactive fallout from nuclear weapons tests in the northern hemisphere and then for fallout from the French nuclear weapons testing programme in the Tuamotu Archipelago. When the French atmospheric radiation testing programme was terminated in 1974, monitoring continued for residues from atmospheric tests and to detect any venting from the underground tests.

Latest report

Any artificial radioactivity continued to be at levels that are below detection limits in many cases and significantly below levels that would give rise to health concerns. No significant change in the radioactivity status of the environment occurred during the period.

No radioactive contamination from the Fukushima Daiichi nuclear accident was observed in the New Zealand environment.
