The objective of this study is to perform a thermo luminescent dosimetry (TLD) postal dose audit provided the International Atomic Energy Agency (IAEA) for a linear accelerator in Dong Nai General Hospital. The TLD were irradiated with an absorbed dose to water of 2 Gy for 6 MV and 15 MV photon beams generated by a linear accelerator (LINAC) (Siemens Medical Solutions, Concord, CA). The percentage deviation relative to IAEA measured dose was 0.4% and 3.4% for 6 MV and 16 MV, respectively. Agreement within ± 5% between the users stated dose and the IAEA measured dose is considered satisfactory. The results showed that all photon beams are within the IAEA’s acceptance limit of ± 5%. As a conclusion, the beam output of Siemens Primus is accuracy in delivery of absorbed dose within ± 5%.
