Comparison of two methods to determine the photon-induced activity of the air around medical accelerators
- 1. Zentralstelle fuer Sicherheitstechnik, Duesseldorf (Germany, F.R.)
Description
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 proportional counter tube ('direct measurement') and by means of activation analyses of imidazole, triazole, malonic acid, and urea specimens ('indirect measurement'). The results are compared. (orig.)
Abstract (German)
Zwei unterschiedliche Methoden zur Bestimmung der durch Bremsstrahlung medizinischer Beschleuniger induzierten Luftaktivitaet werden verglichen. Fuer maximale Photonenenergien zwischen 16 und 42 MeV werden Luftaktivitaetsmessungen mit einem Proportionalzaehlrohr ('direkte Messung') und Aktivierungsanlaysen von Imidazol-, Triazol, Malonsaeure- und Harnstoffproben ('indirekte Messung') einander gegenuebergestellt.
