Comparative Evaluation of Two Analytical Functions for the Microdosimetry of Ions from ¹H to ²³⁸U

Quantum Beam Science
The analytical microdosimetric function (AMF) implemented in the Monte Carlo code PHITS is a unique tool that bridges the gap between macro- and microscopic scales of radiation interactions, enabling accurate microdosimetric calculations over macroscopic

Microdosimetric concepts relevant to HZE-particles [PDF]

, 1977
The biological effectiveness of HZE-particles i s determined by the extreme microscopic concentrations of energy transfer in the vicinity of the particle tracks. The concept of linear energy transfer fails to describe this situation adequately.

Relative Biological Effectiveness (RBE) of Monoenergetic Protons: Comparison of Empirical and Biophysical Models

Applied Sciences
A constant proton relative biological effectiveness (RBE) of 1.1 for tumor control is currently used in proton therapy treatment planning. However, in vitro, in vivo and clinical experiences indicate that proton RBE varies with kinetic energy and ...

Study on Caenorhabditis Elegans as a Combined Model of Microdosimetry and Biology

Dose-Response, 2021
Microdosimetry is a tool for the investigation of microscopic energy deposition of ionizing radiation. This work used Caenorhabditis elegans as a model to estimate the microdosimetric deposition level at the 60 Co gamma radiation.
