Abstract

This paper emphasizes aspects of personnel radiation dosimetry which the authors feel are significant because of present-day inadequacies in dosimetry systems, techniques, and procedures, and because of recently recommended changes with respect to the approaches to dose assessment. In the area of shallow dose measurement the discussion treats weaknesses with respect to badge designs, with emphasis on the common fault of excessive dosimeter coverings and its effect on response. The inability to measure surface doses is discussed in relation to current dosimeter systems, and recommendations are made for designs to measure average doses to the live skin layer. The problems with respect to neutron dosimeters are presented, and tentative suggestions are made for improving responses of these systems. In the area of internal dosimetry, emphasis is on the correlation between uptake, dose, and concentration of the radionuclide in the exposure medium. The significance of the International Commission on Radiological Protection (ICRP) Report 26 is discussed as it relates to approaches to occupational dose assessment.
