A new approach to the dosimetry of mixed radiation using a recombination chamber.
A new method of handling data derived from saturation curves of a recombination chamber is proposed. The method involves formation and extrapolation of a graph y(x), where y and x are simple, well-defined functions of the ratio of the ionisation current of the recombination chamber irradiated in the radiation field investigated to that in the field of a reference gamma radiation, using the same set of voltages, applied consecutively to the chamber. It makes it possible to determine separately the low linear energy transfer (LET) and high-LET components of an absorbed dose and also other important dosimetric quantities characterising a mixed radiation field.
