Comparison of the transport codes HZETRN, HETC and FLUKA for a solar particle event

“…The contribution of these particles to dose and dose equivalent values can be significant. Also, HETC-HEDS uses the NCRP 132 (NCRP, 2000) and 142 (NCRP, 2002) conversion factors in combination with the DABL69 KERMA factors (Ingersoll et al, 1988). The HZETRN code does not use KERMA factors in the calculation of dose and dose equivalent.…”

Comparison of the transport codes HZETRN, HETC and FLUKA for galactic cosmic rays

“…The flux to energy deposited KERMA factors are integrated with the flux to obtain Gray. The neutron energy dependent quality factors are used with the KERMA factors (Ingersoll et al, 1988) to convert the Gray to Sievert. The KERMA factors used by HETC are those for water.…”

“…The contribution of these particles to dose and dose equivalent values can be significant. For low energy neutrons, HETC uses the NCRP 132 and 142 (NCRP, 2002;NCRP, 2000), conversion factors in combination with the DABL69 KERMA factors (Ingersoll et al, 1988). The HZETRN code does not use KERMA factors in the calculation of dose and dose equivalent.…”

“…Future work must correct this.) The number and type of particles used and the algorithm employed for calculating the dose and dose equivalent values are the probable causes for the differences in the dose and dose equivalent curves (NCRP, 2002;NCRP, 1995, NCRP, 2000Ingersoll et al, 1988).…”

Feasibility of an antiproton catalyzed fission fragment rocket

“…Smith characterized this neutron spectrum (Smith, 1991b:2), and it is presented in Figure 5. The tabulated values used in MORSE, divided into 46 energy groups for use with the DABL69 cross section library (Ingersoll and others, 1989), appear in Table 3. These tabulated values were calculated by transforming the data table used to construct Figure 5 (Smith 1991a;2).…”
