| Zusammenfassung | The kerma in the tissue-equivalent material A-150 plastic was determined in monoenergetic neutron fields with neutron energies of 13.9, 15.0, 17.0 and 19.0. MeV and in a collimated neutron beam from Be + d (12.75 MeV) with a broad neutron energy distribution. Three different methods were used. The twin-detector method with a neutron-sensitive and a neutron-insensitive ionization chamber, and a single-detector method with a tissue-equivalent proportional counter were used to measure the photon and neutron kerma components in A-150 plastic. The third method was based on the determination of the spectral neutron fluence at the point of interest and the application of fluence to kerma conversion factors. With the kerma and the spectral neutron fluence data, kerma factors of A-150 plastic were determined. The measured kerma values agreed within 4.5% except for neutrons at 19 MeV. At this energy the experimentally determined A-150 plastic kerma factor is about 11% less than the calculated value obtained from the literature. In the collimated neutron beam the kerma values determined by different methods agreed within 3.3%. |
