Abstract	Traditionally the residual dose rate caused by high-energy hadrons has been parametrized with omega-factors, which relate the dose rate resulting from an activated object to the rate of inelastic hadron interactions within the object. Modern hadron simulation codes allow, in principle, to reach far better accuracy than these rudimentary parameterizations which date back several decades. However, it is shown in this paper that the concept of omega-factors is still useful if these values are properly defined and calculated. Such a re-evaluation, including proper treatment of low-energy neutrons, is given for 19 elements which should cover most of the materials encountered at accelerators.
