The Radiation Health Committee retains the role of setting the allowable limit for microwave leakage from microwave ovens (50 W/m2 at 0.05m) (5mW/cm2 at 5 cm).

“Radiation Health Committee – Radiation Health Series Publication No 17– ARPANSA – Australian Government”.

“The microwave leakage at any point 50mm or more from the external surface of the appliance shall not exceed 50W/m2 (5mW/cm2).”

TI: AS/NZ 60335.2.25 : 2011 Australian and New Zealand Standard SO: Standards Australia / Standards New Zealand

“The power density of microwave radiation emerging from any microwave oven used in a restaurant, a canteen, a hospital, a self service heating unit, a home and the like shall not exceed 5 milliwatts per square centimetre at any point 5 centimetres or more from the external surface of the unit.

Compliance with the 5mW/cm2 limit should be determined using a microwave survey instrument, having specifications outlined below, to measure microwave power density with the probe detector located at 5cm and further from the outer surface of the microwave oven.”

Radiation leakage from electronic equipment presents specials problems because the energy source is not clearly defined…The location of the leakage source has to be found by trial and error.

AS/NZS 2772.2:2011: Radiofrequency fields – Principles and methods of measurement and computation – 3 kHz to 300 GHz SO: Standards Australia / Standards New Zealand

Measurements or evaluations to prove compliance with this Standard must be made by an appropriately qualified and experienced person or authority. Following such measurements or evaluations, and where exposure levels are not increased, the results will remain valid for a period set by the testing authority”.

TI: Radiation Protection Standard Maximum Exposure Levels to Radiofrequency Fields – 3 kHz to 300 GHz SO: Australian Radiation Protection & Nuclear Safety Agency (Australian Commonwealth).

“Exposure to sufficiently high levels of microwaves will cause heating. In the case of human tissue, excessive heating could have serious health effects, such as deep tissue burns and hyperthermia. The purpose of the Australian Standards is to avoid all adverse health effects by limiting exposure levels to levels below those at which heating occurs.”

“This Standard applies to ovens designed for domestic applications, even if used in a workplace.”

SO: ARPANSA (Australian Radiation Protection and Nuclear Safety Agency – Australian Commonwealth), 2006.

“The owner of a microwave oven which is used other than domestic or scientific purposes shall not operate it, or permit it to be operated or used, unless the oven has within the previous 3 years passed a compliance test”

SO: WA Legislation – Radiation Safety Regulations, 1983

“Worksafe Victoria recommends that employers comply with the relevant standards, such as Australian / New Zealand Standard and the National Health & Medical Research Council Standards, in order to demonstrate that they have met their general duty of care under the Act.”
