In the past 5-10 years the concept of the quality factor Q in radiation protection has been widely discussed. Various proposals for Q as a function of LET (linear energy transfer) or y (lineal energy) have been made in order to consider properly the results of radiobiological experiments indicating a higher RBE (radiobiological effectiveness) of neutrons than is expressed by the quality factor for neutrons according to the present convention. A method is presented here for calculating effective quality factors for organ dose equivalents and the operational quantities defined in the ICRU sphere, according to the dose distribution in LET or y. It is shown that all proposed functions for Q, as well as the present convention, lead to photon quality factors considerably in excess of unity for low energy photons. This is in contrast to the need in practical radiation protection where the desirable approximation is that photons of all energies have a quality factor equal to unity. Consequently, there is a need to specify a function of Q which has this property and also leads to a sufficiently high quality factor for neutrons. Such a function is proposed.
