The conventional presentation of only the final results of risk assessments in the form of frequency distributions of health detriments (fatalities) impedes the interpretation and adequate judgement of calculated risks. In particular special questions require information on the space- and time-dependency of radiation doses for individuals and for the population as a whole. For this reason the modified version of the accident consequence model UFOMOD/B3-DOS was developed and extended by various additional computer programs for graphical and numerical evaluations. Special emphasis was laid on the functional connection of frequency, organ dose and number of persons affected, since the calculation of the collective dose in ''manxrem'' is unsuitable for many problems. A systematic scheme of the possible 2- and 3-dimensional graphs facilitates the selection of the appropriate presentation in view of problem-oriented or personal criteria. Examples of frequency-dose diagrams are shown for release categories of the German Risk Study. (orig.). Ehrhardt,-J.; Zoeller,-U
