An absorbed dose‐based source strength determination for diffusing alpha‐emitters radiation therapy (DaRT) brachytherapy seeds – Proof of concept
This work investigated and reported a large dependence of absorbed dose to water on desorption of <sup>224</sup>Ra progeny. An absorbed dose-based source strength specification was proposed with a preliminary design of the apparatus. Using MC methods, the proposed instrument was deemed suitable for source strength measurements with a high sensitivity to changes in the DaRT seed construction.
