Abstract
Exposure to cosmic radiation is a major concern in space exploration. On the
Martian surface, a complex radiation field is present, formed by a constant
influx of galactic cosmic radiation and the secondary particles produced by
their interaction with the planet's atmosphere and regolith. In this work, a
Martian environment model was developed using MCNP6 following the guidelines of
the 1st Mars Space Radiation Modeling Workshop. The accuracy of the model was
tested by comparing particle spectra and dose rate results with other model
results and measurements from the Radiation Assessment Detector (RAD) onboard
the Curiosity rover, taken between November 15, 2015, and January 15, 2016. The
ICRP's voxel-type computational phantoms were then implemented into the code.
Organ dose and effective dose equivalent were assessed for the same time
period. The viability of a mission on the surface of Mars for extended periods
of time under the assumed conditions was here investigated.
