Description/Abstract Gamma radiation effects on RNK and DNK albumen are analyzed and spectra of mouse liver and spleen homogenates and phosphorescence spectra of radioprotection substances at 77 deg K are developed. Tabulated data indicate close coincidence of the wave lengths corresponding to phosphorescence maximums for DNK, radioprotective substances, and gallic acid propylene ethers. It is postulated that the energy transition from the triplet level of DNH to the triplet level of protective substances results in reduced damage to DNK. Moreover, the molecules of the protective substance shift from the ground single level to the triplet. Studies of triplet levels of protective substances help to characterize the energy relation of these substances to the chemical components of biological structures. Preliminary experiments showed that the introduction of propylene gallate and isopropyl gallate reduces the life span of metastable states and dampens the phosphorescence of the albumen. (R.V.J.)
