Estimating the Carbon Footprint of External Beam Radiotherapy: Should This Be a Concern for LMICs?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Purpose This study aims to estimate the carbon footprint associated with external beam radiotherapy in a low‐ and middle‐income country (LMIC) context, specifically at the Uganda Cancer Institute (UCI), and to evaluate whether sustainability should be a priority alongside treatment access in such radiation therapy settings.
