Abstract
The measurements reported are for leakage radiation emerging from the X-ray target housing of a 6 MeV [million electron volts] linear accelerator. Film dosimetry was extensively used to study leakage radiation and served to guide improvements in X-ray head shielding. An ionization chamber study of the leakage component confirmed the film results and provided intensity profiles in 3 orthogonal planes passing through the target. The ionization chamber was also used to measure leakage radiation attenuation and to establish a profile of the useful beam and the penumbral region. For one representative operating condition the leakage and total scatter magnitudes rarely differed by more than a factor of 2 in the therapy room.
