The meaning of safety in radiation protection is considered. Any practice that results in radiation exposures should be subject to a risk-benefit assessment. If the possible risk is acceptable, then the practice should still not be accepted until it is shown by a cost-benefit assessement that the resulting exposure is so low that further dose reductions will not bring about a benefit which justifies the effort. Natural background radiation, medical exposure, occupational exposure and environmental contamination are discussed.
