How does the human exposure standard apply to radiocommunications transmitter installations?
The ACMA’s standard is an exposure standard, not a technical performance standard. A technical performance standard specifies an emission limit, for example, a limit that always applies to field strength or power density at a specified distance from a transmitter. On the other hand, an exposure standard or limit applies anywhere people may be located. In general, for a transmitting facility (including a mobile phone tower) to be non-compliant with the ACMA’s standard, areas where levels exceed the public limits must first be accessible to the public in some way—accessibility is a key to maintaining compliance with the standard. The exposure limit for transmitter installations is stated in Table 7, Appendix C of the ACMA’s publication Human Exposure to Radiofrequency Electromagnetic Radiation – Information for licensees of radiocommunications transmitters. This publication is available from any ACMA office and is on the ACMA’s website. Licensees must block public access to areas where t
