Human exposure to space radiation implies two kinds of risk, both stochastic and deterministic. Shielding optimisation therefore represents a crucial goal for long-term missions, especially in deep space. In this context, the use of radiation transport codes coupled with anthropomorphic phantoms allows to simulate typical radiation exposures for astronauts(More)
We compute the complete set of Feynman Rules producing the Rational Terms of kind R 2 needed to perform any QCD 1-loop calculation. We also explicitly check that in order to account for the entire R 2 contribution, even in case of processes with more than four external legs, only up to four-point vertices are needed. Our results are expressed both in the 't(More)
The nuclear reaction models embedded in the FLUKA code cover hadron, ion, photon and neutrino induced nuclear interactions from energies as low as few tens of MeV up to several tens of TeV. A short description of the main physics ingredients in the FLUKA nuclear models is given, with emphasis on the intermediate energy range and on " exotic " reactions. The(More)
The modeling of ion transport and interactions in matter is a subject of growing interest, driven by the continuous increase of possible application fields. These include hadron therapy, dosimetry, and space missions, but there are also several issues involving fundamental research, accelerator physics, and cosmic ray physics, where a reliable description(More)
We present the results of a Bayesian analysis of solar neutrino data in terms of ν e → ν µ,τ and ν e → ν s oscillations, where ν s is a sterile neutrino. We perform a Rates Analysis of the rates of solar neutrino experiments, including the first SNO CC result, and spectral data of the CHOOZ experiment, and a Global Analysis that takes into account also the(More)
The FLUKA Monte Carlo transport code is widely used for fundamental research, radioprotection and dosimetry, hybrid nuclear energy system and cosmic ray calculations. The validity of its physical models has been benchmarked against a variety of experimental data over a wide range of energies, ranging from accelerator data to cosmic ray showers in the earth(More)
The paper " Bayesian View of Solar Neutrino Oscillations " , by M. V. Garzelli and C. Giunti, lists eight reasons for using Bayesian methods. I shall examine these reasons critically. 1 The Motivation In a recent paper [1] by Garzelli and Giunti, eight arguments are presented in favour of using Bayesian methods for statistical analysis of experimental data.(More)
The FLUKA Monte Carlo code has been evolving over the last several decades and is now widely used for radiation shielding calculations. In order to facilitate the use of FLUKA in dosimetry and therapy applications, supporting software has been developed to allow the direct conversion of the output files from standard CT-scans directly into a voxel geometry(More)
We present a Monte Carlo analysis in terms of neutrino oscillations of the total rates measured in solar neutrino experiments in the framework of frequentist statistics. We show that the goodness of fit and the confidence level of the allowed regions in the space of the neutrino oscillation parameters are significantly overestimated in the standard method.(More)
