[What is the damage gamma-irradiation on solutions-cryoconservants at 77 K?].
Originating under the gamma-radiation action at 77 K on glassy phosphate solutions (6 mol/l) of glycerol and glycero-1-phosphate, H-atoms have motility by virtue of tunneling effect and react with the stabilized radicals of a matrix (OH /H2O+) and with solutes: at storage them in liquid nitrogen the radicals of separation H from carbon atoms C1 and C2 will be derived. According to the assessment maximal radiation "damage" is plotted to the investigated system for year, approximately 1 mol/l.
