Abstract

It is widely known that radiation therapy is used for treating cancer. One of the modalities for treating cancer is linear accelerator (LINAC) which utilizes high frequency electromagnetic waves to accelerate charged particles through a linear tube. However it is important to maintain the accuracy of output produced by LINAC. As stated in TRS-398, the requirement for accuracy in radiation therapy should be ±5% of the prescribed dose. This research is aimed to measure the radiation dose and 2 accuracy from LINAC in 10 x 10 cm radiation field using ionization chamber and TLD chips in 6 MV, 15 MV, 6 MeV, and 9 MeV energy levels. In photon and electron beam, measurement using ionization chamber, the range of error was small from 0 Gy to ±0.2024 Gy. On the other hand, the range of error in the measurement using TLD chips was higher from ±0.0001 Gy to ±0.3912 Gy. In conclusion, measurement using TLD chips had slightly higher errors compared to the measurement using ionization chamber.
