SPERA holds biennial conferences across the South Pacific region.

The purpose of these conferences is to promote communication among scientists in the field of environmental radioactivity. Scientists from many different disciplines and organisations from the South Pacific region and countries worldwide will come together to discuss and debate the origins and behaviour of natural and anthropogenic radionuclides in the environment; their radiological consequences and the practices required to minimise these; and their application to the understanding of natural processes.

Next Conference:

CANBERRA, Australia

14 – 17 September 2026

In 2026 the 18th international SPERA conference (SPERA2026) will be held in Canberra, Australia. The conference will be hosted by the Department of Nuclear Physics and Accelerator Applications, at the Research School of Physics, Australian National University.
