Abstract
The proposed method involves determination of ratio of absorbed doses in a mixed radiation field due to radiations from two different sources, provided that both radiations are of different LET, hence of a different quality factor. A detector used in the method is a tissue-equivalent recombination chamber. Shape of saturation curve of such a chamber depends on LET (on radiation quality). If the shapes of saturation curves are known for the radiations from two sources or for both components of a two-component radiation, then the actual ratio of absorbed dose components created simultaneously by these radiations in the mixed radiation field can be determined, performing relatively simple measurements of the ionization current at two different polarizing voltages applied to the chamber.
