This Radiation Protection Standard sets limits for human exposure to radiofrequency (RF) fields in the frequency range 3 kHz to 300 GHz. The Standard includes: (1) mandatory basic restrictions for both occupational and general public exposure involving all or part of the human body; (2) indicative reference levels for measurable quantities derived from the basic restrictions; (3) approaches for verification of compliance with the Standard; and (4) requirements for management of risk in occupational exposure and measures for protection of the general public. The document goes well beyond simply being a technical Standard. The working group of the Radiation Health Committee that drafted the document put an immense amount of work into reviewing the scientific literature. Annexes to the Standard include a summary of the review of epidemiological studies of exposure to RF and human health and research into bio-effects at lower levels of exposure.This Standard was approved by the Radiation Health Committee on 20 March 2002. On 12 April 2002 the Radiation Health & Safety Advisory Council advised the CEO that the Standard might be considered for adoption.
