During the radiation therapy with electron beam, due to electron interaction
and scattering from structures of the head of the medical linear accelerator,
unwanted photons are produced. In order to measure photon contamination
at the electron mode of the ELEKTA Precise linear accelerator, thermoluminescence
detectors (TLD700 & GR200) at two energies (10 & 15MeV)
in polyethylene phantom were applied. Our result shows the rate of
produced bremsstrahlung photons dose for points close to the phantom
which is located in radiotherapy room of the Arak Ayat-O-lah Khansari
hospital are in mSv range
