On the role of LET-dependent parameters in the determination of the absorbed dose by in-phantom recombination chambers
Natalia Golnik , Maciej Grzegorz Maciak
AbstractThe paper discusses the theoretical background in terms of the use of in-phantom recombination chambers in mixed radiation fields, with special attention paid to the question of how the experimentally determined, linear-energy-transfer-dependent (LET) parameters can be applied with regard to the more accurate determination of the chamber response and absorbed dose in mixed radiation fields. Methods of taking the recombination index of radiation quality (RIQ) measurements and theoretical consideration concerning the determination of the absorbed dose are described. Classical Bragg-Gray and Spencer-Attix cavity theories were analysed and their relationship to in-phantom recombination chambers was specified. Methods concerning the estimation of correction factors with regard to RIQ measurements and their importance are highlighted.
