Radiation is considered one of the most complex problems for long duration manned and unmanned missions, therefore it is important to mitigate the effects of radiation. One solution widely studied is by taking advantage of spacecraft material properties and their ability to protect against radiation. Studies usually analyze the radiation performanc...

Context 1
... on suggestions from past research and material composition, the materials chosen for this study are polyethylene, polyurethane, Nylon6, Kevlar49, SWCNTs, MWCNTs, poly allyl diglycol carbonate, and Boron Carbide. Table 1 shows the density, composition, atomic weight, and atomic density of each material, which are values important in determining the radiation damage. Table 2 shows the values for the basic elements. ...

... 5 main elements. First, the user can input the carbon, hydrogen, nitrogen, boron, and oxygen content of the material. This is simply how many atoms of each element is in the composition. Inputting the elemental composition allows analysis of composite materials and even nanomaterials. For this study, the materials that will be used are listing in Table 1. The elemental properties from Table 2 are also incorporated into the code. The other inputs needed are the incident particle energy experienced, and the particle flux. For this study, the particle energy will be a single value of 1 MeV and 10 MeV. The code has not yet been developed to incorporate particle flux, but considering it is simply a linear relationship it can ...
