Description
The spectral energy deposition in small volumes by 60Co gamma-rays and by 200 kV X-rays was measured with a walled spherical counter, a walled cylindrical counter and a wall-less cylindrical counter. The simulated volumes had dimensions of 0.1-3 μm. By comparing the spectra of the spherical and cylindrical walled counters the influence of the counter shape is derived. The wall effect is discussed by comparing the spectra and the mean linear energy measured with the walled and the wall-less cylindrical counters. The influence of the counter size and of radiation quality on the energy deposition spectra is also analysed. (orig.)
Abstract (German)
Die spektrale Energieabgabe in kleinen Volumen durch 60Co γ-Strahlen und 200 kV Roentgenstrahlen wurde mit einem kugelfoermigen Zaehler mit Wand, einem zylindrischen Zaehler mit Wand und einem wandlosen zylindrischen Zaehler gemessen. Die simulierten Volumen hatten Abmessungen von 0,1-3 μm. Der Einfluss der Zaehlerform wurde durch einen Vergleich der Spektren der kugelfoermigen und zylindrischen umwandeten Zaehler ermittelt. Der Wandeffekt wird bestimmt, indem man die Spektren und die mittlere lineare Energie der umwandeten und der wandlosen zylindrischen Zaehler vergleicht. Der Einfluss von Zaehlergroesse und Strahlenqualitaet auf die Energieabgabespektren wird ebenfalls diskutiert. (orig.)Additional details
