Extensive monitoring for radon gas was conducted throughout Western Australia in the 1990's. Radon gas levels were found to be slightly higher in the hills areas when compared to levels found on the coastal plain but these levels were not above accepted international and national recommended limits. Levels of radon gas in Western Australian homes are significantly below levels encountered in many Western European countries and also the United States of America.
