Survival of model organisms exposed to UV-C radiation. The percent survival (y axis logarithmic scale) is plotted versus dose of UV radiation (x axis linear scale) for human fibroblasts [41], Escherichia coli [42], Saccharomyces cerevisiae [43], Halobacterium sp. NRC-1 (in the dark or in presence of visible light) [11], and Deinococcus radiodurans [44].
