The TW with a thickness of 3\u00a0cm simulating the thoracic wall was used (upper layer). The TW or TL with a thickness from 1 to 15\u00a0cm (1\u00a0cm increments) was placed beneath the upper layer (middle layer). The TW with a thickness of 5\u00a0cm simulating the mediastinum was placed beneath the middle layer (lower layer), and a farmer ionization chamber was placed beneath this layer. The relative doses of a 10 MV X\u2010rays were then measured. The TL was compensated in 1 mm increments from 1 to 11\u00a0mm of the STR, and the thickness of the STR at the same dose of TW (water equivalent) was obtained.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The compensating ability of STR increased as the thickness of the TL increased, and an STR with a thickness of 1\u00a0mm reduced the dose by 2%\u20134%, depending on the thickness of lung.
