| Abstract: | The calculation of the radiation environment caused by galactic cosmic rays with Monto Carlo method has been investigated.The model setup method and the variance reduction technics usually used in the calculation are analysized.The spectra of secondary particles resulting from interactions of primary galactic cosmic rays with the nuclei in the atmosphere calculated by Roesler with FLUKA code and by Anid with MCNPX code are discussed and compared to a large variety of experimental data.One method to assess t... |
