Recombination Chambers—do the Old Ideas Remain Useful?

Recombination methods were invented almost contemporaneously with the introduction of the ICRU/ICRP concept of a radiation quality factor expressed in terms of linear energy transfer. Since then, recombination chambers and related methodologies have been extensively developed, along with new concepts of dosimetry and radiation protection. This article briefly presents the main features of recombination chambers and their possible applications in practical systems for measuring dosimetric quantities.
