Abstract: A recent discovery concerning the importance of hadron production in space radiation is that pions can contribute up to twenty percent of the dose from galactic cosmic ray interactions (S. Aghara, S. Blattnig, J. Norbury, R. Singleterry, Nuclear Instruments and Methods, Vol. 267, 2009Vol. 267, , p. 1115. Although the contribution for dose equivalent will be smaller, the dose contribution could be important for fluence based radiation models. Pion production cross sections will be an essential ingredient to su… Show more

“…Although it was simulated, the pion contributed no fluence for proton secondary particles in the therapeutic energy range because the pion production threshold in nucleon-nucleon reactions is at 280 MeV. [20] Figure 3 shows the energy deposition curves of different particles obtained from MCNPX for 160 MeV protons in a water phantom. Although the fluences of neutrons and photons were only one order smaller than that of protons, their contributed dose was about 0.1-1% of the proton dose.…”
