9.1.6 Development Of Australian Standards
Australia initially relied on administrative guidance, workplace procedures, and overseas exposure criteria. As scientific understanding and domestic use of RF systems increased, a dedicated Australian exposure standard was published in 1985. It was subsequently revised as dosimetry, thermal physiology, and international guidance developed.
A joint Australian and New Zealand exposure standard followed in the 1990s. In 2002, the Australian Radiation Protection and Nuclear Safety Agency published Radiation Protection Series No. 3, which provided Australia with a national RF exposure standard extending from 3 kHz to 300 GHz.
Australia's current national exposure standard, ARPANSA RPS S-1, was published in 2021 and aligns its exposure limits with the ICNIRP 2020 Guidelines. It specifies basic restrictions, reference levels, compliance principles, occupational risk-management requirements, and measures for protecting the general public.
Australia and New Zealand now apply different national exposure-limit documents, but they continue to share AS/NZS 2772.2, which provides principles and methods for RF measurement and computation. This illustrates the distinction between a document that establishes exposure limits and one that describes how exposure is assessed.
9.1.7 International Harmonization
As wireless equipment and services became global, substantial differences between national exposure standards created difficulties for regulators, manufacturers, employers, and workers. International harmonization therefore became an increasingly important objective.
Scientific and standards organizations developed systematic processes for reviewing biological, medical, dosimetric, and engineering evidence. The International Commission on Non-Ionizing Radiation Protection became particularly influential through its development of science-based exposure guidelines. The IEEE also developed a comprehensive and independently reviewed framework for human exposure to electromagnetic fields.
Many countries have adopted or adapted recommendations from these organizations. Complete uniformity has not been achieved because legal systems, regulatory responsibilities, terminology, and implementation practices differ between jurisdictions. Nevertheless, contemporary standards generally share a common scientific foundation and distinguish between internal basic restrictions and externally assessable reference levels.
International guidelines do not automatically become law. Their legal effect depends upon how they are adopted through national legislation, regulations, license conditions, workplace requirements, or other enforceable instruments.
