The authors report on the specific radioactivity of construction components of a 42 MeV betatron measured 28 days after the last run by means of a Ge spectrometer (ultra-pure germanium detector employed in a semiconductor spectroscopic method) recording the gamma spectra of various components of the betatron. This examination served to find out which(More)
Using the medical linear electron accelerator SL 75/20 supplied by Philips and employing a radiation time of 15 minutes with the 16 MeV high-energy photon stage, we measured the radioactivities induced by photons and neutrons, at the output elements (target, compensator body, wedge filter, diaphragms), at the positioning table of the patient and at a barium(More)
The authors compare two different methods to determine the activity of the air induced by the bremsstrahlung of medical accelerators. The activities of the air resulting from maximum photon energies of 16 to 42 MeV are measured with a proportional counter tube ("direct measurement") and by means of activation analyses of imidazole, triazole, malonic acid,(More)
