Comparison of GEANT4 Simulation of Atmospheric Cosmic Rays with Measured Terrestrial Muon and Neutron Spectra
نویسندگان
چکیده
A Monte Carlo simulation of primary protons and alpha particles interacting with the atmosphere has been performed using the GEANT4 code. Measured particle fluxes were used as input to the simulation. The simulated terrestrial cosmic ray flux was found to agree within a factor of two with the measured neutron flux over the energy range from 1 to 10,000 MeV and with the measured muon flux in the momentum range from 0.2 to 85 GeV/c.

Correlation Studies of Cosmic Ray Flux and Atmospheric and Space Weather
Since 1950’s there has been a growing interest of understanding the effects of cosmic ray radiation on the increase in average global temperature. Recent studies showed that galactic cosmic rays play a significant role in the formation of low cloud coverage and its consequent impact on the global temperature variation of the earth. A long-term measurement of the cosmic ray flux distribution at ...

Geant4 has been used to estimate the rate, energy spectrum and angular distribution of cosmic ray muons at underground depths between 300 and 1000 m.w.e. The results agree well with those from the MUSIC program when the same surface spectrum is used. Care has been taken to use a parameterization of the surface spectrum which agrees well with data for the relevant energies. 1 Goals Knowledge of ...

Muon tomography (MT) based on the measurement of multiple scattering of atmospheric cosmic ray muons traversing shipping containers is a promising candidate for identifying threatening highmaterials. Since position-sensitive detectors with high spatial resolution should be particularly suited for tracking muons in a MT application, we propose to use compact micro-pattern gas detectors, such as ...

Crews working on present-day jet aircraft are a large occupationally exposed group with a relatively high average effective dose from galactic cosmic radiation. Crews of future high-speed commercial flying at higher altitudes would be even more exposed. To help reduce the significant uncertainties in calculations of such exposures, the male adult voxels phantom MAX, developed in the Nuclear Ene...

Imaging and identifying materials with high atomic numbers and densities, especially radioactive materials, is one of the issues that have been especially considered in recent years. Due to some limitations in conventional and old imaging techniques, finding an alternative method is very important. The cosmic muons with an infinite source are one of the sources that have been recently studied f...
