Linking Microdosimetric Measurements to Biological Effectiveness in Ion Beam Therapy: A Review of Theoretical Aspects of MKM and Other Models

Frontiers in Physics, 2021
Different qualities of radiation are known to cause different biological effects at the same absorbed dose. Enhancements of the biological effectiveness are a direct consequence of the energy deposition clustering at the scales of DNA molecule and cell ...

Energy-Loss Straggling and Delta-Ray Escape in Solid-State Microdosimeters Used in Ion-Beam Therapy

Journal of Nuclear Engineering, 2022
Microdosimetry is increasingly adopted in the characterization of proton and carbon ion beams used in cancer therapy. Spectra and mean values of lineal energy calculated in frequency and dose are seen by many as the tools which, by complementing ...

Microdosimetry

Istituto Lombardo - Accademia di Scienze e Lettere - Rendiconti di Scienze, 2023
The interest in the application of microdosimetry for assessing the radiation quality of hadrontherapy fields has grown in the last two decades. The reference detector for microdosimetry is the tissue-equivalent proportional counter (TEPC). Novel types of microdosimeters have been developed by the Nuclear Measurement Laboratory of the Politecnico di ...
