In the field of radiation protection, quality factor Q(L) and radiation weighting factor w_R are important coefficients for estimating both radiation protection and operational quantities to the mixed types of radiation exposure. However, some inconsistencies might be found between Q(L) and w_R for estimating effective dose, for example. Some inconsistencies are attributed to incomplete definition of terms Q(L) and w_R. This report presents the root and evolution of quality factor Q(L) and radiation weighting factor w_R for the years 1931-2007, to clarify the current issues of inconsistencies to be solved.
