      More Details Abstract Fulltext PDF

      A simulation of the radiation field inside a habitable module (a diameter of 6 m and length of 12 m) of a spacecraft generated by isotropic Galactic Cosmic Radiation (GCR) in deep interplanetary space is carried out for minimum and maximum solar activity using the FLUKA code. Protons, alpha-particles,deuterons, ${}^3$He, and nuclei with $Z$ > 2 are considered as primary GCR irradiating the spacecraft isotropically. The following particles are included in FLUKA radiation transport through the module shell (15 g/cm$^2$ of Al): protons, neutrons, $\gamma$-rays, electrons, $\pi^{\pm}$-mesons, $\mu^{\pm}$-mesons d, t, and nuclei from He to Ni. The inner particle spectra are needed to assess the astronaut’s radiation risk in a long-term interplanetary mission.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
