Listen "RadPhysics E15a: Brachytherapy Physics - Sources, Strength & Dose Calculation"
Episode Synopsis
Welcome back to the RadOnc Smart Review Physics Series! We've thoroughly covered external beam therapy. Now, we're shifting gears dramatically to explore treatments where the radiation source is placed inside or very close to the target. In Episode P15a: Brachytherapy Physics - Sources, Strength & Dose Calculation, we'll introduce the common radioactive isotopes used, discuss how their strength is properly quantified, and meticulously break down the fundamental TG-43 formalism used for calculating dose around these sources.
