Abstrakt: The article discusses research on X-ray-induced deterioration of disulfide bridges at atomic resolution at temperatures of 100 and 15 degrees Kelvin (K). The study showed that the changes occur at doses below 1.4 X 107 gray (Gy) and small changes occur at higher doses. The study found that the dose, required to induce the same deterioration of the disulfide bonds and atomic displacements at 15 K, is more than two times higher than those at 100 K.
