Neutron dosimetry
R É S U M É En dosimétrie des neutrons, les situations pratiques rencontrées couvrent un large domaine d'énergie s'étendant sur plus de 10 décades. En outre, les grandeurs dosimétriques utilisées en radioprotection ne sont pas directement accessibles à la mesure. Ce dernier point est principalement dû à la variation de la "qualité" du rayonnement neutronique, exprimé au moyen des facteurs de po...
متن کاملNeutron Dosimetry and Neutron Spectrum Unfolding Using Neural Networks
An artificial neural network has been designed to obtain the neutron spectra from the Bonner spheres spectrometer's count rates. The neural network was trained using 101 neutron spectra taken from IAEA's compilations. These include calibration, reference and operational neutron spectra whose energy distribution is different from UTA4 response matrix, therefore the spectra were converted from le...
متن کاملDosimetry in Mixed Neutron-Gamma Fields
The gamma field accompanying neutrons may, in certain circumstances, play an important role in the analysis of neutron dosimetry and even in the interpretation of radiation induced steel embrittlement. At the figh Flux Isotope Reactor pressure vessel the gamma-induced reactions dominate the responses of ' W p and 238u dosimeters, and9Be helium accumulation fluence monitors. The gamma induced at...
متن کاملA novel approach to neutron dosimetry.
PURPOSE Having been overlooked for many years, research is now starting to take into account the directional distribution of neutron workplace fields. Existing neutron dosimetry instrumentation does not account for this directional distribution, resulting in conservative estimates of dose in neutron workplace fields (by around a factor of 2, although this is heavily dependent on the type of fie...
