Shielding assessment for multi-ion radiotherapy based on ion-specific dose-defined workloads

Ui-Seob Lee, Y. M. Goh, Geum Mun Back, Chul Hee Min et autres

The expansion of heavy-ion radiotherapy toward multi-ion operation requires a reassessment of shielding design methods that have traditionally relied on particle-number-based workloads. In facilities employing multiple ion species, this approach becomes inconsistent because different ions require substantially different numbers of primary particles …
