Welcome

Welcome to the Oceania Radiofrequency Scientific Advisory Association Inc.  (ORSAA)
 
ORSAA is a not-for-profit organisation of scientists and professionals of various academic disciplines who are interested in the scientific research that investigates the effects of artificial electromagnetic radiation (EMR) on humans, animals and the environment. As the name indicates, ORSAA has a special focus on radiofrequency electromagnetic radiation (RF-EMR) that includes high frequency microwaves widely used for wireless communication and surveillance technologies. However, ORSAA’s interest in biological effects research extends to extremely low frequency (ELF) fields such as those utilized for domestic electrification (power frequencies).
 
ORSAA’s ethos is to provide an independent perspective on the relevant science and facilitate evidence-based decision making by various stake-holders of modern society including clinicians, educators, safety officers and policy makers on issues regarding exposure to EMR.

Scientific Evidence of Biological Effects
Findings of biological and health effects of RF-EMR date back to the 1940s during early stages of microwave usage for radar and medical diathermy. With increasing interest, particularly from the military, the field of RF bio-effects research continued to grow. The World Health Organization (WHO) co-sponsored an international symposium in 1973 entitled Biologic Effects and Health Hazards of Microwave Radiation and later established the International EMF Project in 1996.
 
In 1994 the Australian government commissioned, a review on RF biological effects by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The implications of biological effects in human health was addressed in a Senate Inquiry in 2001.
 
At present (2019), the scientific literature in this area is comprised of several tens of thousands of peer-reviewed studies. As with scientific research on other environmental pollutants, RF-EMR research is complex and contains inconsistencies; some studies showing significant effects while others are showing no effects. The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has conducted reviews of the scientific literature since 2000 for the Australian government and is also the owner of the RPS3 exposure standards.

The Precautionary Principle
The WHO’s International Agency for Research on Cancer (IARC) classified RF-EMR as a Group 2B possible human carcinogen in May 2011.
 
Based on the current status of scientific research, ORSAA recommends a Precautionary Approach with regard to exposure to artificial EMR – both RF and ELF fields.
