Abstract/OtherAbstract:
A model for the induction of transformation, mutation, and cell killing by radiations of intermediate to high linear energy transfer (LET) is presented. The mathematical formulation presupposes a constant probability per unit path length for damaging multiple subcellular targets by radiation of a fixed LET. The coupling between effects is accounted for through an explicit calculation of the probability that any specific combination of effects occurs in a given cell. This feature avoids the false assumption that cell killing and mutation (or transformation) are independent events. The resulting model then is applied to data on the in vitro survival, mutation, and transformation of cells by radiations of varying LET. A summary of estimated parameter values is provided and calculations of the effect of cellular flattening on transformation are presented.
