[Pharamagnetic centers developing during irradiation of gamma-phos].

The ESR spectra's of X-irradiated radioprotector gamma-phos have been studied. Using the analysis of relaxation effects in this sample irradiated at room temperature three paramagnetic centers have been discovered. One of these centers is classed with the free radical approximately CH2--CH--CH2 approximately (R1)-G(R1) value decreases with a decrease of irradiation temperature. Free radicals R1 are not oxidized in the air. Two other of paramagnetic centers have not been identified.

[Relation between the radioprotective effect of helium-neon laser radiation on bacterial cells and the time period between 2 types of irradiation].

The effect of helium-neon laser radiation (lambda = 633 nm) given to E. coli K-12 cells of various genotypes 4 h following X- or alpha-irradiation was shown to increase the number of viable cells. The irreversible ingradient of a radiation injury to cells remained invariable during the first 60 min after irradiation its values being minimal.

[Modification of the damaging effect of alpha-particles on Escherichia coli K-12 by low-intensity laser irradiation].

A study was made of the combined effect of laser (helium-neon laser, lambda = 633 nm) and alpha-radiation on survival of Escherichia coli K-12 cells of different genotypes. Pre- and post-irradiation exposures to laser-radiation diminished the damaging effect of alpha-particles. In the latter case, modification of survival was more pronounced.
