Integration of macrodosimetry with microdosimetry; Biological dose estimation method adopting lineal energy y instead of LET as the index for expressing RBE

Sato, Tatsuhiko   

Integration of macro-dosimetry with micro-dosimetry is of great importance for the improvement of various dosimetric researches such as biological dose estimation for charged-particle therapy. This article explains the difference of the concepts between micro-dosimetry and macro-dosimetry, and reviews our recent works related to the establishment of the model for calculating the microscopic lineal-energy distributions in macroscopic matters. Our developed biological-dose-estimation method based on lineal energy instead of LET is also described in this report.
