The purpose of the study was to use TLD-100 (LiF:Mg,Ti) thermoluminescence dosimetry to assess the outfield radiation dose received by a breast cancer patient during hypofractionated radiation therapy. The element correction factor system was used to assess the variability of the thermoluminescence dosimetry’s (TLD) responses. Sixteen TLD-100 chips were placed in nine specific areas in the Rando phantom for point doses in organs outside the treatment fields during breast cancer radiation treatment (260 cGy × 16 = 41.6 Gy in 16 fractions). The thermoluminescence signals were read out by a Harshaw QS-3500 manual type reader connected to a PC, where the readings were analyzed. The maximum dose values were received in the esophagus (≈3960 cGy) and trachea (≈3464 cGy). The TLD-100 chips can be used to calculate point doses in hypofractionated radiotherapy, making them very useful for ensuring accurate and precise treatment of patients.
