This research investigates the impact of radiation exposure from hadrons of terrestrial cosmic rays (primarily neutron, proton, and pion) on solid-state storage devices, specifically focusing on the transient effects that cause single event upsets (SEUs) or soft errors. The experiment involves measuring soft-error rates of a commercially available solid-state storage device controlled by NodeMCU micro-controller when exposed to hadron beams from the T9 PS accelerator that simulate terrestrial cosmic radiation exposure. In particular, we propose to test the shielding efficacy of different origami geometric radiation shield designs, bio-mimetically inspired by the cellular structure of radiation resistant Melanized fungi. The proposed experiment draws on two strands of previous studies -- radiation induced soft errors in solid state devices, and geometric cellular structure of radiation-resistant fungi in shielding. The results of this study will potentially contribute to the development of new bio-mimetic origami geometric design philosophies and principles for radiation shield designs.
