%X Dosimetric characteristic is one of the essential parameters of a medical linear accelerator (LINAC), which must be obtained before clinical use. The dosimetric characteristics for 6 MV photon beam were measured and compared with the corresponding published data. The study was done using a Varian linear accelerator (Model Clinac-iX) at the Institute of Nuclear Medical Physics (INMP), AERE, Savar, Dhaka, under the Bangladesh Atomic Energy Commission (BAEC). The data is taken for 10 field sizes (2 ¡Á 2, 3 ¡Á 3, 5 ¡Á 5, 7 ¡Á 7, 10 ¡Á 10, 15 ¡Á 15, 20 ¡Á 20, 25 ¡Á 25, 30 ¡Á 30 and 40 ¡Á 40 cm<sup>2</sup>) at same conditions. The measured Percent Depth Dose (PDD) curves were obtained for 6 MV photon beams with the field as mentioned above and compared with the calculated PDD curves. The measured depth dose (D<sub>max</sub>) for reference field size (FS) 10 ¡Á 10 cm<sup>2</sup> is 15.99 mm, and the PDD at 10 cm depth (D<sub>10</sub>) is 66.87% for 6 MV photon energies that are found to be compatible with the published report BJR supplement 25. The measured PDD curves for photon energies show a good agreement with the standard PDD curves. The photon beam dosimetry data found in the current study are compatible and all the tolerances are within the clinically acceptable tolerance limit.
