In the NASA Space Radiation Cancer Risk models 2010 and 2012 (NASA, 2011, 2013), the concept of a risk cross section was introduced to relate the cancer risk directly to the physical quantity of the charged particle fluence appearing in the organs of a space traveler. Since this approach is a modification of the conventional way of relating the absorbed dose to the risk through a quality factor...
