claimThe fungi Cladosporium sphaerospermum and Cremonium murorum, isolated from the walls of Chernobyl Reactor 4, extract energy from the emitted ionizing radiation present in that environment.
referenceMoeller R et al. reported in 2014 that the resistance of Bacillus subtilis spore DNA to lethal ionizing radiation relies primarily on spore core components and DNA repair mechanisms, with oxygen radical detoxification playing a minor role.
claimHaloarchaea are polyextremophilic microbes that can withstand salinity, anaerobic conditions, high ultraviolet and ionizing radiation levels, subzero temperatures, desiccation, and toxic ions.
referenceBauermeister et al. (2011) examined the effect of relative humidity on Deinococcus radiodurans' resistance to prolonged desiccation, heat, ionizing radiation, germicidal radiation, and environmentally relevant UV radiation, published in Microb Ecol 61:715–722.
claimChroococcidiopsis spp. have been evaluated for their resistance to both sparsely and densely ionizing irradiation in a 2017 study by Verseux et al.

claimExperimental simulations of the Martian surface incorporate high levels of UV and ionizing radiation, severe desiccation, and a chemically reactive regolith enriched with oxidants like perchlorates and hydrogen peroxide.
measurementDeinococcus radiodurans can survive acute doses of ionizing radiation exceeding 15,000 Gy, a tolerance level 1000 times higher than that of humans.
referenceC. Verseux et al. evaluated the resistance of the cyanobacterium Chroococcidiopsis spp. to sparsely and densely ionizing irradiation, published in Astrobiology in 2017.

measurementThe Agribalyse 3.1.1 database utilizes 14 specific metrics to assess environmental impact: greenhouse gas emissions (kg CO2 eq), exposure ionizing radiation (kg U235 eq), photochemical ozone formation (kg NMVOC eq), ozone depletion (Freon-11), emission of particulate matter (mortality due to particulate matter emissions), acidification (mol H+ eq), terrestrial eutrophication (mol N eq), freshwater eutrophication (kg P eq), marine eutrophication (kg N eq), freshwater ecotoxicity (CTUe), water use (m3 world eq), land use (loss of soil organic matter content in kg carbon deficit), fossils resource use (MJ), and metals and minerals resource use (kg Sb eq).
