The humanoid phantom was irradiated to a reference dose of 10 Gy, limiting the lung dose to 7.5 Gy. The ratio of the average measured dose midplane in the craniocaudal direction to the reference dose was 1.001 with a spread of \u00b14.7% (1 sd). Dose to the lung was measured in 26 locations and found, in average, 1.8% lower than expected. Lung dose was homogeneous in the ventral\u2010dorsal direction but a dose gradient of <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/mp6355-math-0003.png\" xlink:title=\"urn:x-wiley:00942405:media:mp6355:mp6355-math-0003\"\/> was observed in the craniocaudal direction midline within the lung lobe. 3D dose calculations (Pinnacle<jats:sup>\u00ae<\/jats:sup>) were found, in average, 2% lower compared to dose measurements on the body axis and 3% lower for the lungs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>The alanine\/EPR dosimetry system allowed accurate dose measurements which enabled the authors to validate their TBI dose protocol.
