As a comparison, radiation workers at ANSTO receive, on average, an exposure above natural background levels of 0.6 millisieverts a year â well under the maximum occupational limit of 20 millisieverts annually.
Average exposures to background radiation. In Australia people receive about 1.5 - 2.0 'millisieverts' of ionising radiation every year. This is natural background radiation. Low exposure to ionising radiation is not harmful. Passengers on high-altitude flights get more exposure to cosmic radiation than at ground level. For example, if you flew return from Sydney to Los Angeles you would get 0.16 millisieverts of radiation dose.
