NEUTRON SPECTROMETRY AND DOSIMETRY WITH ANNs
Artificial Neural Networks technology has been applied to unfold the neutron spectra and to calculate the effective dose, the ambient equivalent dose, and the personal dose equivalent for Cf and AmBe neutron sources. A Bonner sphere spectrometry with a LiI(Eu) scintillator was utilized to measure the count rates of the spheres that were utilized as input in two artificial neural networks, one f...
متن کاملPredicting Neutron Production from Cosmic-ray Muons
Fast neutrons from cosmic-ray muons are an important background to underground low energy experiments. The estimate of such background is often hampered by the difficulty of measuring and calculating neutron production with sufficient accuracy. Indeed substantial disagreement exists between the different analytical calculations performed so far, while data reported by different experiments is n...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملNeutron 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 کاملPion and neutron production by cosmic-ray muons underground.
The production of positive pions and neutrons by cosmic muons at underground sites of various depths is investigated. We first test the equivalent photon method in the particular case of ∆ excitation by the muon. We find that this method, when it neglects the momentum dependence of the transverse response, reproduces remarkably well the theoretical muon cross section. This success has lead us t...
