Background and purpose: High-energy photon beams above 8-10 MV used in external radiation therapy produce neutron in dealing with the linear accelerator components and other parts in radiation field. The weakening of neutrons due to the closing jaws collimator angle, in smaller field sizes can also be a contributing factor in changing the neutron spectrum. Since a direct measurement of the...
