      Abstract

      It appears that further attempts to achieve reduction in radiation dose through the use of higher HVL, increased filtration, and higher voltage will not be productive. It is suggested that optimum levels for present equipment and films lie within the ranges now in use. Further research into radiation protection probably should be directed along other avenues.
      The diagnostic quality of films rather than dosage considerations must continue to be of primary concern in the light of inadequate knowledge of genetic damage and the availability of adequate radiologic health measures. It is necessary that the accepted physical factors used in producing roentgenograms be flexible, thereby achieving a favorable balance between the benefits derived from diagnosis and the hazard of mutation.
