[Effective energy values of 90 degree scattered photons during urological and bronchial fluoroscopy].
During fluoroscopic bladder and bronchial examinations the radiation workers concerned are exposed to 90 degrees--scattered photons. The effective energy expressed in mm AI was measured for these photons exited at tube potentials in the 60--100 kV RANGE. An increase also depends on whether the measurements are made in the direction of the long axis or the short axis of the phantom. These findings are contrary to the recommendations stipulated in the code of practice SABS 07-1972.
